Brewer's Blackbird

Brewer's Blackbird - Euphagus cyanocephalus

A bird to be seen in the full sun, the male Brewer’s Blackbird is a glossy, almost liquid combination of black, midnight blue, and metallic green. Females are a staid brown, without the male’s bright eye or the female Red-winged Blackbird’s streaks. Common in towns and open habitats of much of the West, you’ll see these long-legged, ground-foraging birds on sidewalks and city parks as well as chuckling in flocks atop shrubs, trees, and reeds

Size & Shape
  • A small, fairly long-legged songbird with the well-proportioned look of many blackbirds: the fairly long tail is balanced by a full body, round head, and long, thick-based beak. In perching males, the tail appears widened and rounded toward the tip.
Color Pattern
  • Males are glossy black all over with a staring yellow eye and a blue sheen on the head grading to greenish iridescence on the body. Females are plainer brown, darkest on the wings and tail, with a dark eye. Immature birds look like washed out, lighter-brown versions of the females.
  • Brewer’s Blackbirds feed on open ground or underfoot in parks and busy streets. Their long legs give them a halting walk, head jerking with each step almost like a chicken’s. In flocks, Brewer’s Blackbirds rise and fall as they fly. At landing, birds may circle in a slow fluttering flight before settling.
  • Look for Brewer’s Blackbirds in open habitats of the West, such as coastal scrub, grasslands, riversides, meadows, as well as lawns, golf courses, parks, and city streets.

This afternoon I ran the usual bike path route out and back. Easy and short. My legs are sore. I will need a couple more days of easy runs to recover. My mileage won't be as high as I expected this week. I hope to have at least two runs over one hour and one long run this week. Total run time: 33 minutes.

On Tuesday morning I hit the hills. I ran a very hilly course with an elevation gain of 1,400 feet. My legs were sore but I kept an even pace throughout of the run. It started with a 19 minutes climb followed by  10 minutes downhill. Then a 23 minutes climb followed by some rolling hills for about 8 minutes. The last section was downhill.(the same section that I ran uphill at start) Total run time: 1 hour and 9 minutes.

On Tuesday afternoon I went out for another run. I ran from home to the bike path out and back, and headed back home. I stopped to do a few pull ups. My run was a little too fast on the bike path. It became almost a tempo run for about 20 plus minutes. I felt light and comfortable with the pace. Great warm weather. Total run time: 51 minutes and 30 seconds.

On Monday I did an easy short run. My legs were feeling very sore. I ran the usual bike path route out and back. I am recovering well. My intent is to put a high mileage week and gradually back off. My next race is in about three weeks. It is a hilly ten mile race. Total run time: 33 minutes.

Sunday, April 24, 2011


This morning I got up ready to race. But the weather changed quickly. The rain came down and I changed my mind. My right hamstring still sore and I don't want to aggravate my injury. My diet has not been the best in the last few days. I 'd like to taper properly before a race. Add the tired legs due to my work, and it was the right decision.
Since racing was out of question, I went for a long run under a rainy skies. I chose a very hilly route, right out of my  front door. It started with a 15 minutes long climb on the this paved road followed by a big drop in elevation. I got a break for about 10 minutes on the flat section of the paved road. Then things went up again for another 25 minutes or so. The rest of the route was a mix of  flat and downhill paved roads and trails, Total run time: 1 hour and 56 minutes.

On Saturday I did a short run from home, followed by a few easy relaxed strides. I was testing my legs to see if I could run on Sunday. Things seem to be improving but I'll know for sure tomorrow morning. My right hamstring still a little sore. It showed a lot improvement since my last race. Total run time: 30 minutes.

On Friday I ran the bike path route out and back. My legs were a little tired. The allergies were really bad and with all the rain that we had it made things worse. I had too many days off this week. Not a very good habit. But sometimes work becomes priority and by the end of day, there is nothing legs left.
Total run time: 32 minutes.

On Thursday  I decided to take another day off. I was feeling very tired.

Curing Aging

By Bill Andrews, Ph.D. and Jon Cornell

Since before recorded history began, people have been searching for ways to live longer. We all know the story of Ponce de Leon's search for the elusive Fountain of Youth, but even two millennia earlier, emperor Qin Shi Huang of China was sending out ships full of hundreds of men and women in search of an Elixir of Life that would make him immortal. The desire to live forever is as old as humanity itself.
But it has only been in the last thirty years that science has made any real progress in understanding the fundamental question of why we age and what can be done about it. These discoveries have not been widely publicized-yet -and so most people are unaware of how close we are to curing the disease of aging once and for all.


Is Aging a Disease?

References to "the disease of aging" still make many people uncomfortable. After all, aging is a natural process that has existed forever -so how can it be a disease?

In fact, aging has not existed forever. Approximately 4.5 billion years ago, a cell came into existence on Earth that was the progenitor of every living organism that has since existed. This cell had the ability to divide indefinitely. It exhibited no aging process; it could produce a theoretically infinite number of copies of itself, and it would not die until some environmental factor killed it. When the ancestry of any given cell is traced back to this very first living cell, this lineage is called the cell's germ line.

Much later -perhaps three billion years later- some cells of the germ line began to form multicellular organisms: worms, beetles, lobsters, humans. The germ line, however, was still passed on from one generation to the next, and remained immortal. Even with the inclusion of multicellular organisms, the germ line itself exhibited no aging process.

But, in some multicellular organisms, such as humans, certain cells strayed from the germ line and began to exhibit signs of aging. These cells aged because they became afflicted with a disease: their ability to reproduce themselves indefinitely became broken. The cause of this disease is still speculative, but many scientists are searching for cures.

The fact that a disease has existed in the genetic code of an animal for a very long time does not mean that it is not a disease. Thousands of diseases, from hemophilia to cystic fibrosis, have lurked in our genes for far longer than recorded history. These diseases should be cured, and aging is no exception.

The Cause of Aging

The root cause of aging is very straightforward: we age because our cells age.
In 1961, Leonard Hayflick, a researcher at the Wistar Institute in Philadelphia, discovered that there was a limit to the number of times a human cell could divide.1 After about 70 divisions, a cell derived from embryonic tissue enters a stage where its ability to divide slows and eventually stops. This stage is called cellular senescence. Hayflick also observed that the number of times a cell could divide was governed by the age of the cells: cells from a twenty-year-old could divide more times than cells from a fifty-year-old, which in turn would divide more times than cells from a ninety-year-old.
Hayflick discovered that, in essence, there is a clock ticking inside every dividing cell of our body. Our aging process isn't simply a consequence of accumulated damage: there is a specific property of our cells that limits how long we can live.

The nature of this property was proposed independently in the early 1970s by both Soviet and American scientists.2 When a cell divides, the genetic material inside that cell needs to be copied. This process is called DNA replication. These scientists suggested that the limitation on cell division is rooted in the very nature of DNA replication. The enzymes that replicate a strand of DNA are unable to continue replicating all the way to the end, which causes the loss of some DNA.

As an analogy, think of a DNA as a long row of bricks, and of DNA replication as a bricklayer walking backwards on top of a brick wall laying a new layer on top of that row. When the end of the wall is reached, the bricklayer finds himself standing on top of the brick he's supposed to replicate. Since he can't put down a brick where his feet are, he steps back and falls off the wall - leaving the very end of the wall bare.  As a result, the new copy of the wall is shorter.

Just like this brick wall was copied imperfectly, our DNA is unable to perfectly copy itself; when a strand is replicated, the new strand is shorter than the old strand.

If we lost portions of the information encoded in our DNA every time it replicated, human life would be impossible. Our cells couldn't even divide enough times to allow us to be born. Fortunately, we are born with long, repetitive sequences of DNA at the end of each of our chromosomes, which later shorten during the normal DNA replication process.

These repetitive sequences are called "telomeres."

Telomeres, like all DNA, are made up of units called nucleotides, arranged like beads on a string. The nucleotides in human telomeres are arranged in the repeating sequence TTAGGG (two thymine nucleotides, one adenine nucleotide, and three guanine nucleotides). This sequence is repeated hundreds of times in tandem in every telomere.

Each time our cells divide and our chromosomes replicate, our telomeres become shorter. When we are first conceived, the telomeres in our single-cell embryos are approximately 15,000 nucleotides long. Our cells divide rapidly in the womb, and by the time we are born, our telomeres have decreased in length to approximately 10,000 nucleotides. They shorten throughout our lifetime, and when they reach an average of about 5,000 nucleotides, our cells cannot divide any further, and we die of old age.
Leonard Hayflick had discovered that there was a clock ticking in every dividing cell of our body; telomere shortening explains what makes that clock tick.
The time remaining on this "telomere clock" can be measured from our blood cells. When such measurements are taken, a significant correlation is found between a person's age and the number of "ticks" remaining on the person's clock.



Obviously, there must be a way for our bodies to re-lengthen telomeres. Otherwise, our sperm and egg cells would contain telomeres the same length as the rest of our cells, which would yield embryos as old as we are. Because so much cell division takes place in the womb, our children would then be born much older than us. Humanity could not exist more than a generation or two if this were the case.

However, our reproductive cells do not exhibit telomere shortening, and show no signs of aging. They are essentially immortal. They are our germ line - the same one that has been dividing since the beginning of life on this planet.

The reason these cells are immortal is that our reproductive cells produce an enzyme called telomerase. Telomerase acts like an assembly line inside our cells that adds nucleotides to the ends of our chromosomes, thus lengthening our telomeres.

In a cell that expresses telomerase, telomeres are lengthened as soon as they shorten; it's as though every time the "telomere clock" inside our cells ticks once, telomerase pushes the hands of the clock back one tick.

Telomerase works by filling the "gap" left by DNA replication. Returning to the analogy of the bricklayer that can't lay the last brick on the brick wall, telomerase would be like an angel that flies in and puts the last brick in place.

Telomere Length Therapy

So what about us? Can we insert the telomerase gene into all of our cells and extend our lifespan?
Inserting the gene directly into our DNA, through the use of viral vectors, is not a viable option. The main problem with this approach is that inserting genes into cells often causes cancer. That's because the gene gets inserted into our chromosomes at random sites, and if the wrong site is chosen, the gene can interrupt and disable cancer suppressor genes or turn on cancer-inducing genes. And you only need one out of the hundred trillion cells in your body to become cancerous in order to kill you.
Fortunately, the telomerase gene already exists in all our cells. That's because the DNA in every one of our cells is identical: a skin cell, muscle cell, and liver cell all contain exactly the same genetic information. Thus, if the cells that create our sperm and egg cells contain the code for telomerase, every other cell must contain that code as well.

The reason that most of our cells don't express telomerase is that the gene is repressed in them. There are one or more regions of DNA neighboring the telomerase gene that serve as binding sites for a protein, and, if that protein is bound to them, telomerase will not be created by the cell.
However, it is possible to coax that repressor protein off its binding site with the use of a small-molecule, drug-like compound that binds to the repressor and prevents it from attaching to the DNA. If we find the appropriate compound, we can turn telomerase on in every cell in the human body.

Compounds such as these have very recently been discovered. One such compound is TA-65, a nutraceutical discovered by Geron Corporation and licensed to TA Sciences. Additionally, Sierra Sciences, using a robotically-driven high-throughput drug screening effort, has discovered over two hundred compounds in twenty-nine distinct drug families that induce the expression of telomerase in normal cells. However, the perfect drug hasn't been found yet. None of the compounds induce telomerase in large enough quantities that are likely to stop or reverse aging; even the strongest known compound, a synthetic chemical patented by Sierra Sciences but not approved for human use, induces only 16% of the telomerase expression found in some immortal cell lines. Also, many of these compounds (with the notable exception of TA-65) are somewhat toxic to cell cultures and probably unsafe for human consumption.
Finding a more powerful drug will require more screening and more research, and the speed of that progress is dependent almost entirely on the level of funding that the project can achieve.

Proofs of Principle

There is a plan in place for inducing telomerase in all our cells. But will that plan work? Will it cure aging? That's the trillion-dollar question, and scientists have been trying to answer it for more than a decade. So far, all the signs point to yes: telomerase is a very likely cure for aging.

In 1997, scientists inserted the telomerase gene into normal human skin cells grown in a Petri dish. 5 When they observed that the telomerase enzyme was being produced in the cells, as hoped, they also observed that the skin cells became immortal: there was no limit to the number of times these cells could divide. When the lengths of the telomeres in these "telomerized" cells were examined, the scientists were surprised to see that the telomeres didn't just stop shortening: they got longer. The critical question, then, was whether the cells were becoming younger.

A few years later, scientists inserted the telomerase gene into human skin cells that already had very short telomeres. These cells were then grown into skin on the back of mice.6 As one would expect, skin from cells that hadn't received the telomerase gene looked like old skin. It was wrinkled, blistered easily, and had gene expression patterns indicative of old skin.
The skin grown from cells that had received the telomerase gene, on the other hand, looked young! It acted like young skin, and, most importantly, its gene expression patterns, as analyzed by DNA Array Chip analysis, were almost identical to the gene expression patterns of young skin. For the first time ever, scientists had demonstrably reversed aging in human cells.

Would the concept apply to living organisms? In November 2008, scientists published a paper describing how they had created cloned mice from mouse cells containing the inserted telomerase gene, which continually produced the telomerase enzyme. 7 These mice were shown to live 50% longer than cloned mice created from cells that didn't contain the inserted telomerase gene.
It's becoming increasingly clear that prevention of telomere shortening might be the best way to extend human lifespan beyond the theoretical 125-year maximum lifespan. How long this can extend the human lifespan is anyone's guess, but living a healthy, youthful life to 250, 500, or even 1,000 years is not outside the realm of possibility. More research needs to be done to answer that question.

The Cancer Question
The ability to divide forever and never age describes our ancestral germ line, but it also describes a much less pleasant type of cell line: cancer.
A cancer begins when something goes wrong in a cell, causing it to lose control over its growth. It begins to divide repeatedly, ignoring chemical signals that tell it to stop. However, the telomeres continue to shorten in these cells, and eventually, the cells reach a stage where they can no longer divide, at which point they enter a "crisis mode."

In the vast majority of cases, when this crisis is reached, the cells will enter senescence and stop dividing. However, very occasionally, they will find ways to re-lengthen their telomeres. When this happens, a cancer begins to divide not only uncontrollably but indefinitely, and this is when cancer becomes truly dangerous.

In most cases (85-95%), cancers accomplish this indefinite cell division by turning on telomerase. For this reason, forcing telomerase to turn off throughout the body has been suggested as a cure for cancer, and there are several telomerase inhibitor drugs presently being tested in clinical trials.
So, anti-aging scientists must be out of their minds to want to turn the telomerase gene on, right?
No! Although telomerase is necessary for cancers to extend their lifespan, telomerase does not cause cancer. This has been repeatedly demonstrated: at least seven assays for cancer have been performed on telomerase-positive human cells: the soft agar assay, the contact inhibition assay, the mouse xenograft assay, the karyotype assay, the serum inhibition assay, the gene expression assay, and the checkpoint analysis assay. All reported negative results. 8

As a general rule, bad things happen when telomeres get short. As cells approach senescence, the short telomeres may stimulate chromosome instability.9 This chromosome instability can cause the mutations normally associated with cancer: tumor suppressor genes can be shut off and cancer-causing genes can be turned on. If a mutation that causes telomerase to be turned on also occurs, the result is a very dangerous cancer.

Paradoxically, even though cells require telomerase to become dangerous cancers, turning on telomerase may actually prevent cancer. This is not just because the risk of chromosome rearrangements is reduced, but also because telomerase can extend the lifespan of our immune cells, improving their ability to seek out and destroy cancer cells.

It's fairly obvious that long telomeres in human beings are not correlated with cancer. If that were true, young people would get cancer more often than the elderly. Instead, we usually see cancers occurring in people at the same time they begin to show signs of cellular senescence - that is, at the same time their immune system begins to age and lose its ability to respond to threats. Extending the lifespan of our immune cells could help our bodies fight cancer for much longer than they presently can.

Objections to Finding a Cure

There are some who claim that a cure for aging is not a good thing, and that this is a technology that should never be researched in the first place. Some of the most common concerns about extending human lifespan are listed below, along with responses to these objections.
"Won't the Earth become overpopulated?"
It stands to reason that extending our lifespans would increase the world population; after all, we've seen it happen before. In just over a century, the average life expectancy of a person living in the United States has increased from 47.3 in 1900 to 78.0 in 2008. Technologies including vaccines, antibiotics, chemotherapy, and antioxidants, as well as social advances such as sanitation, environmentalism, and an anti-smoking crusade have all contributed to this. Most recently, we've made attempts to push our lifespans out even further with technologies such as hormone replacement, caloric restriction, and Resveratrol.

And, indeed, these technologies have increased the size of our population. But something interesting also happened: population growth rate began to slow. Birthrates fell rapidly, and in less than four decades, the average number of children in a family was more than cut in half, from 6 to 2.9. Today, most researchers think we are headed quickly towards a stable population. Evidence is mounting that humans will simply not reach populations larger than our ability to sustain them: economics preclude us from doing that. As resources become scarce, prices rise, and as prices rise, family sizes shrink.
Is it a bad thing that our medical advances have nearly doubled our life expectancy? Most would say it's a decidedly good thing. So it's probably a safe bet that if we can drastically increase that figure again, future generations will also look back on it as beneficial.
"Won't Social Security be bankrupted?"
Social Security is quickly heading toward bankruptcy right now - and the reason lies in the very nature of aging.

A typical person today works for forty to fifty years before retiring at age 65 or shortly thereafter. Although retirement is often framed as a reward earned by a lifetime of hard work, the truth is that, not too long after reaching age 65, people inevitably become too sick and weak to continue working even if they wanted to. That's not the most desirable of rewards.

The fundamental problem with Social Security is that many of our modern medical advances have extended our lifespan, but have not expanded our healthspan to match. In 1935, when Social Security began, only about 57% of the population survived to age 65, and those who did only lived an average of 13 more years. Today, nearly 80% of the population survives to 65, and those who do typically live 17 more years.10

But these aren't our highest-quality years of life. Extending lifespan without improving healthspan has given us a large number of people who remain sicker longer, putting a historically unprecedented burden on the healthy to care for the sick.

If we felt as healthy and energetic at age 65 as we do at 30, why would we want to permanently retire? It would be far cheaper for the government to pay for a worker to take a ten-year vacation after forty years of work than to pay for seventeen years of decline and the staggering health care costs that accompany it. Not only that, but ten years of vacation as a healthy, youthful individual sounds like a much better reward for decades of hard work than seventeen years of decline.
"Isn't curing aging unnatural or sacrilegious?"
Certainly, it can be argued that a cure for aging is unnatural. But it can also be argued that a human being, in his or her most natural state, is cold and hungry, infested with parasites, vulnerable to predators, and generally lives a life that Hobbes famously described as "nasty, brutish, and short."
In our natural state, we are susceptible to the disease of aging, and, similarly, we are susceptible to the disease of smallpox. Yet few among us would look back and claim that we made a horrible mistake when we unnaturally eradicated smallpox.

Sometimes, objections to finding a cure for aging are made on religious or philosophical grounds: some see such a cure as a defiance of natural order or of God's will. However, there are also many people whose religions and philosophies are exactly what drives them to seek a cure for aging. For example, Christian writer Sylvie Van Hoek believes that the search for the cure is not only compatible with belief, but that belief compels us to seek a cure:
The Book of Genesis speaks of God's love. The creation stories describe the perfect world He created for us. After each creation He confirmed that it was good. There was no death or suffering in the Garden of Eden because it was not part of His plan. It couldn't have been because all that God creates is good; everything that is not good is the result of the absence of God. It was original sin that corrupted our perfect world. In failing to resist temptation and wanting to be like God---by eating from the forbidden tree of knowledge---man and woman turned away from God. This transformed the beauty of our nakedness into something shameful. Shame was impossible before the sin because nakedness meant that we enjoyed an intimate relationship with God. It was the sin that marked the beginning of our struggle with physical and moral suffering. Suffering is always the death of something, so physical death is just the far extreme along that same continuum.

Critics [of anti-aging science] should read A Theology of the Body by John Paul II (Pauline Books, Boston, 2006). The recent pope eloquently expands on every bit of scripture concerning the body.

In fact, I view [anti-aging science] as very much comporting to God's plan. He never wanted this for us. He created a different world, one that we corrupted. He could have turned away from us as we did to Him, but instead He sent the Christ to save us.  He continues to work in the world today because He wants us to be happy. You may think you're doing something coldly scientific by fighting aging, but you're already up to your eyeballs in the fight against evil.11
There may be some who will always have philosophical and religious concerns about anti-aging science. But aging can be a painful, torturous process: it seems difficult to argue that going through the final stages of decline is an inherently good thing, or that finding a way for all of us to remain fit and healthy is inherently evil.
"Won't future generations face challenges, such as long-lived dictators, that could have been avoided?"
The short answer is yes. But the same can be said of any technology. When humans invented the car, we also created the problems of traffic safety and air pollution. When we invented factories and industrialized the manufacture of goods, we were forced to rebuild ancient economic and social structures. When we discovered fire, we also had to learn not to get burned.

But, looking back, we wouldn't have it any other way. Any progress comes with its own challenges, but rejecting progress because we don't trust future generations to deal with it is not the solution.

Other Cures for Aging

There are many theories on what causes aging,12 and they may all be true - different pieces of the puzzle of why we grow old. These theories can be looked at as multiple sticks of lit dynamite inside our cells, each stick of dynamite representing a different cause of aging. It's only the stick of dynamite with the shortest fuse that will kill us.13 Which theory of aging has the shortest fuse? No one knows for sure, but given the well-established correlation between telomere length and age, telomere shortening is a good bet.

Scientists around the world are looking for cures for aging, and control of telomere length is not the only one being discussed. In fact, there might even be better ways.

One approach that's receiving a lot of attention is stem cell therapy. Stem cell therapy actually works on a principle similar to telomerase activation; the idea is to periodically infuse the body with young cells to replace cells that have senesced.

Some scientists feel that curing cellular senescence is only a single piece of the aging puzzle, and that aging must be addressed on other fronts. An example is Aubrey de Grey's "Strategies for Engineered Negligible Senescence"; De Grey believes that a cure for aging must include therapies that address not only cellular senescence but also cancer-causing mutations, mitochondrial mutations, intracellular junk, extracellular junk, cell loss, and extracellular crosslinks.

There are also theoretical approaches to curing aging which appear to be scientifically sound, but for which the technological groundwork has not fully been laid. These include nanotechnological methods of intelligently repairing cellular damage, where infinitesimally small robots could be programmed to maintain the body at an optimal state of health. Another exciting concept is "mind uploading" technology, in which the brain would be regularly scanned into a computer to safeguard it against damage to the body. Although it's unlikely that these technologies will come to fruition in the very short term, they do merit further research.

Ultimately, our goal is to extend our lifespans and healthspans and live a young, healthy life for as long as possible. Telomerase activation may or may not be the "magic bullet" needed to achieve that end, but it's a technology that's well within reach, and any extension of lifespan could allow us to live long enough to see the next technology developed.

To extend our lifespans indefinitely, all we need to do is enter a period of scientific progress where technologies that extend our lifespans more than one year are discovered each year. Authors Ray Kurzweil and Terry Grossman have coined a phrase to describe this strategy: "Live long enough to live forever."

In Conclusion

People often wonder why progress in finding a cure for aging isn't moving faster. A common impression is that aging cures are well-funded, but the science is out of our reach. That simply isn't true. The primary reason that aging isn't already cured is because of lack of funding.

What is most needed in order to find ways to extend our lifespan before that lifespan runs out on us is for the wealthy individuals that want to see aging cured in their lifetime to get together, review all the approaches that exist for curing aging, prioritize them, and then fund the ones on the top of the list. Besides lengthening telomeres, some of the candidates for funding were described in the previous section.

This kind of patron investment is the only plausible way to lay down a path to the cure for aging. The government doesn't support this kind of research, and venture capital is more focused on short-term profits than long-term cures.
If aging is cured in our lifetime, it will be because of these patrons, not because of brilliant leaps of intuition on the part of any scientist. When it comes to curing aging, the science is fairly straightforward; the funding is not.

Allergy Medications

Several types of medications are used to treat allergy symptoms. Discover which ones are right for you.

Allergy medications reduce your body's reaction to allergens or block symptom-causing chemicals such as histamine. Allergy medications are available as pills, liquids, nasal sprays, eyedrops, skin creams and shots (injections). Some allergy medications are available over-the-counter, while others are available by prescription only. Here's a summary of various types of allergy medications.


Corticosteroids help prevent and treat inflammation by blocking allergic reactions. Most corticosteroids require a prescription.

  • Oral corticosteroids (pills and liquids) are used to treat severe symptoms caused by all types of allergic reactions. Examples include prednisone (Prednisone Intensol) and prednisolone (Prelone, others). Because they can cause numerous short- and long-term side effects, oral corticosteroids are usually prescribed for short periods of time. Long-term use can cause cataracts, osteoporosis, muscle weakness and delayed growth in children.
  • Nasal corticosteroid sprays prevent and relieve allergy signs and symptoms such as nasal stuffiness, sneezing, and itchy, runny nose. Examples include fluticasone (Flonase), mometasone (Nasonex), budesonide (Rhinocort Aqua), flunisolide (Nasarel), triamcinolone (Nasacort AQ) and beclomethasone (Beconase AQ). Side effects can include unpleasant smell or taste, nasal irritation, and nosebleeds. These medications are much less likely to cause side effects than are oral corticosteroids.
  • Inhaled corticosteroids are used to relieve asthma symptoms triggered by allergens. Examples include flunisolide (Aerobid), triamcinolone (Azmacort), fluticasone (Flovent) and budesonide (Pulmacort). Side effects don't tend to be bothersome for most people, but can include an infection in the mouth, cough, hoarseness or headache.
  • Corticosteroid eyedrops are used to treat severe allergy signs and symptoms such as red, watery and itchy eyes caused by hay fever and allergic conjunctivitis. Examples include dexamethasone (Maxidex, others), fluorometholone (FML, others) and prednisolone (Pred Forte, others). These medications may cause blurred vision. Prolonged use may increase your risk of eye infections, glaucoma and cataracts.
  • Corticosteroid skin creams relieve the scaling and itching caused by eczema (atopic dermatitis). Some low-potency corticosteroid creams are available without a prescription, but you should always talk to your doctor before using any topical corticosteroid. Examples include hydrocortisone (Cortaid, others) and triamcinolone (Kenalog, others). Side effects can include skin irritation and discoloration.


Antihistamines block histamine, an inflammatory chemical released by your immune system during an allergic reaction.
  • Oral antihistamines (pills and liquids) reduce signs and symptoms such as swelling, runny nose, itchy, watery eyes, and hives (urticaria). Over-the-counter oral antihistamines include loratadine (Claritin), cetirizine (Zyrtec) and clemastine (Tavist). Fexofenadine (Allegra) is available by prescription. Some oral antihistamines may cause dry mouth and drowsiness. Older, "first generation" antihistamines such as diphenhydramine (Benadryl) and chlorpheniramine (Chlor-Trimeton) are more likely to cause drowsiness and slow your reaction time. These older, sedating antihistamines shouldn't be taken when driving or doing other potentially dangerous activities, and shouldn't be given to children or older adults.
  • Antihistamine nasal sprays help relieve sneezing, itchy or runny nose, sinus congestion, and postnasal drip. Prescription antihistamine nasal sprays include azelastine (Astelin, Astepro) and olopatadine (Patanase). Side effects of antihistamine nasal spray may include bitter taste, dizziness, drowsiness or fatigue, dry mouth, headache, nasal burning, nosebleed, nausea, runny nose, sore throat, and sneezing.
  • Antihistamine eyedrops are often combined with other medications such as mast cell stabilizers or decongestants. Antihistamine eyedrops can reduce itching, redness and swollen eyes. You may need to use these medications several times a day, as the effects may last only a few hours. Over-the-counter examples include ketotifen (Zaditor, Alaway, others), naphazoline (Visine-A, Opcon-A, others). Prescription examples include naphazoline (Albalon, others), emedastine (Emadine) and olopatadine (Patanol, others). Side effects of these medications can include red eyes, watering eyes, headache, and mild stinging or burning. Antihistamine eyedrops increase the risk of eye inflammation when you're wearing contact lenses.


Decongestants are used for quick, temporary relief of nasal and sinus congestion. You may need to avoid decongestants if you're pregnant, you're older, or you have high blood pressure.

Oral decongestants (pills and liquids) relieve nasal and sinus congestion caused by hay fever. Many decongestants are available over-the-counter. Examples include pseudoephedrine (Sudafed, others). A number of medications contain a decongestant such as pseudoephedrine combined with other medications. Claritin-D, for example, contains pseudoephedrine and an antihistamine. Oral decongestants can cause a number of side effects, including irritability, fast or irregular heartbeat, dizziness, insomnia, headaches, anxiety, tremors and increased blood pressure. Check with your doctor before using oral decongestants, as these medications are potentially dangerous if you take certain other medications or if you have high blood pressure (hypertension), heart disease or certain other health problems.
  • Nasal decongestant sprays relieve nasal and sinus congestion. Examples include phenylephrine (Neo-Synephrine, others) and oxymetazoline (Afrin, others). Nasal decongestants can cause dryness, burning or stinging inside the nose, runny nose and sneezing. Taking too much of a nasal decongestant can cause irritability, fast or irregular heartbeat, dizziness, insomnia, headaches, anxiety, tremors and increased blood pressure. Don't use a decongestant nasal spray for more than a week or so, or you may develop severe congestion as soon as you stop taking it (rebound congestion).
  • Decongestant eyedrops (or combined decongestant-antihistamine eyedrops) can temporarily ease symptoms such as red, itchy eyes. Available over-the-counter, examples include tetrahydrozoline (Visine, Clear Eyes, others). Side effects include persistent eye redness and damage to blood vessels in the eye when overused. Rarely, this medication causes a type of sudden (acute) glaucoma.

Other allergy medications

A few other medications work by blocking symptom-causing chemicals released during an allergic reaction.
  • Montelukast (Singulair) is a prescription medication that blocks symptom-causing chemicals called leukotrienes. This oral medication relieves allergy signs and symptoms including nasal congestion, runny nose and sneezing. Side effects can include upper respiratory infection in adults, and headache, ear infection and sore throat in children. The Food and Drug Administration (FDA) has warned that leukotriene-blocking medications could possibly cause psychological symptoms, such as irritability, anxiousness, insomnia, hallucinations, aggression, depression, suicidal thinking and suicidal behavior, in some people.
  • Cromolyn sodium (NasalCrom) is an over-the-counter nasal spray. It prevents the release of histamine and other symptom-causing chemicals during an allergic reaction. This medication works best when you take it before your symptoms start. Some people need to use the spray three or four times a day. Side effects may include nasal stinging or sneezing.
  • Mast cell stabilizer eyedrops prevent the release of symptom-causing chemicals such as histamine during an allergic reaction. These prescription medications reduce allergy symptoms such as red, itchy eyes. Examples include cromolyn sodium (Crolom), lodoxamide (Alomide), pemirolast (Alamast) and nedocromil (Alocril). These medications don't usually cause noticeable side effects.


Immunotherapy injections (allergy shots) may relieve hay fever symptoms or allergic asthma that doesn't improve with medications, or you aren't able to take allergy medications without side effects. Over a period of three to five years, you receive regular injections containing allergen extracts. The goal is to desensitize you to specific allergens and decrease or eliminate your need for medications. Immunotherapy may be especially effective if you're allergic to cat dander, dust mites, or pollen produced by trees, grass and weeds. In children with allergic rhinitis, immunotherapy may help prevent the development of asthma. Rarely, immunotherapy injections can cause a severe allergic reaction (anaphylaxis).

Emergency epinephrine shots

An epinephrine shot stops a severe allergic reaction. These self-injecting syringe and needle (autoinjector) devices include Twinject, EpiPen and EpiPen Jr. You may need to carry an autoinjector if you're likely to have a severe allergic reaction to a certain food, such as peanuts, or you're allergic to bee or wasp venom. A severe allergic reaction can cause anaphylactic shock — a sudden, life-threatening reaction. Epinephrine is a form of adrenaline that can help slow the reaction while you seek emergency treatment.
If you do carry an emergency epinephrine shot, be sure to replace it by the expiration date or it may not work correctly.

Work with your doctor

Work with your doctor to help you avoid problems and choose the most effective allergy medications. Even over-the-counter allergy medications have side effects, and some allergy medications can cause problems when combined with certain other medications.
It's especially important to talk to your doctor about taking allergy medications if:
  • You're pregnant or breast-feeding.
  • You have a chronic health condition such as diabetes, glaucoma or high blood pressure.
  • You're taking any other medications, including herbal supplements.
  • You're treating allergies in a child. Children need different doses of medication or different medications from those that adults use. Some medications, such as corticosteroids, can cause side effects in children.
  • You're treating allergies in an older adult. Some allergy medications can cause confusion, urinary symptoms or other side effects in older adults.
Keep track of your symptoms, when you use your medications, and how much you use — that way you and your doctor can figure out what works best. You may need to try a few different medications to determine which ones are most effective and have the least bothersome side effects for you.



On Wednesday I did a short run on the bike path. Easy and relaxed. My legs were fired. Hope to recover for the Sunday's race. The rain came back and the pollen was everywhere. I have never seen anything like this. We had so much rain and now a horrible allergy season. Total run time: 32 minutes and 30 seconds.

On Tuesday I HAD to take a day off. I kicked a 6x6x6 wood block by accident. My left foot became so painful I could not even walk. It was a day off forced on me by the natural laws of psychics.

Monday is always an easy day. I ran the usual bike path route. Damn! The allergy season is quite bad this year. The bagel doctors are saying that it is the worse allergy season in the last 25 years. They recommend to take lots druggies to solve your running nose, sneezing, coughing, barking, biting and other problems caused by the excess of pollen in the air. You can even have access to  all these medications that used to be by prescription only. Well, the bagels already had access to all these druggies. Their tribe doctors used to give them free prescriptions with no restrictions, way before these druggies were available over the counter. Total run time: 33 minutes.

On Sunday my legs were feeling a little better. I left home around 8AM in direction to my local track. It has been a long time since I have done a speed session on the track. After 15 minutes of a quick warm up, I ran 1.5 miles in 8 minutes. The plan was to test my racing pace. During the first 200 meters I was running with the wind in my back, but as I turned the corner for the other 200 meters I had to face the wind. It slowed me down less than a couple seconds. Overall I felt good even that my legs were tight. I will have lots work to do if I will be racing again on Sunday.  Total run time: 59 minutes.

On Friday I did an easy run. My legs are very sore and tight. Another easy short day should help me. I ran the usual bike path route and stopped to do a few pull ups. Total run time: 33 minutes.

On Saturday I ran on the local track for 4.25 plus miles. Easy and relaxed. I rode my bike to the track and back home. I did some drills to loose up my legs and arms. Total run time: 29 minutes and 54 seconds on lane 5.

The Flying Bagels

 I will try to update this article as the flying bagels become more and more visible to the human eye. If you see one, please, contact me. I want to share your experiences of being adopted by a flying bagel and your experience inside of their spacebagel. Did they perform a circumcision at your privaties? Did you identify the smelly space rabbi?

Quick list of highly probable or confirmed UFO hoaxes and myths:

It took me only thirty seconds to find another flying bagel story: Hoax in the Bagel Land

For anyone who still sees a UFO through the sea of red flags, there’s the video analysis that shows evidence of fakery. Robert Sheaffer, a longtime skeptical UFO investigator and author of the Bad UFOs blog told Life’s Little Mysteries that, “the original Jerusalem UFO has now been definitely shown to be a hoax. Effects of the video processing software are clearly seen. The hoaxer used Motion Tile effects with edge mirroring to introduce camera shake into the video. You can see the mirroring effects along the edge of the video. This proves that the video did not go directly from the camera to YouTube, that it made a stop in between inside a sophisticated video editing software suite. Once you start editing it like that, a skilled hoaxer can put practically anything in it.”

Ray Santilli "Roswell alien autopsy" film (1995) - Ray Santilli fake "Roswell Alien Autopsy film" and "Roswell crash wreckage" videos aired in 1995, are a confirmed hoax (see Eamonn investigates "Alien Autopsy" 2002 TV documentary or quick summary of Eamonn on Santilli hoax and comments by Philip Mantle) and Kiviat on AA film. Santilli changed his story in 2002 and admitted to have filmed a dummy alien, created by sculptor and special-effects designer John Humphreys. The organs were made from sheep and chicken offal, the leg injury made use of a sheep bone joint. The set was a terraced house in Camden Town, London. The actors included Santilli, Shoefield, Humphreys, and one of Shoefield's employees, Gareth Watson.

Santilli claimed to have done a "restoration", as the supposedly original film footage was worn out and practically unusable, but it is practically certain that the entire affair was a hoax and Santilli doesn't admit it to avoid fraud charges.

Bob Lazar (supposedly worked on UFO back-engineering project at "S4" Area 51 in Nevada USA,  bogus UFO propulsion physics involving Element-115 aka Ununpentium) - Bob Lazar UFO physics (see discussions at Lazar corner) Ununpentium-115 superheavy element, gravity waves type A and type B. I could potentially believe (based on his name being listed in Los Alamos National Laboratory 1982 phone book and his tax return slip citing payment from Department of Naval Intelligence) that Lazar has worked at S4 / Area-51 and even has seen flying saucers as he claims, but his "flying saucer physics" with element Uup-115 creating a "gravity A wave" which extends outside the nucleus and then amplified and "out of phase gravitational waves" etc, I find impossible. Critiqued by David Morgan and Friedman.

John Searl (claims to have flown what he called an IGV -Inverse Gravity Vehicle- in England during the 1960s)

TNT's "KGB UFO Files" alien autopsy video and film of half-buried discoid UFO which supposedly crashed in 1968 in Sverdlovsk (Berezovsky) Russia - The supposed UFO crash in 1968 in Sverdlovsk (Berezovsky) Russia and subsequent alien autopsy in "The secret KGB UFO Files" TV documentary by TNT with Roger Moore (James Bond 007) hosting, is a confirmed hoax Shurinov critique, Alex Hefman on TNT KGB UFO Files hoax

Project SERPO (alleged top-secret exchange program between the US government and an alien planet called Serpo) - SERPO Project about a supposed top secret exchange program of twelve US military personnel to Serpo, a planet of Zeta Reticuli, between the years 1965-78.

Project Bluebeam (conspiracy theory aimed at Christian fundamentalists since the 1990s) -
Project Blue Beam (3-dimensional holographic projection of 'Jesus' in the sky). Photography issues: "orbs" (backscatter orbs) and "rods".

UMMO (hoax spread mostly in Spain & France in the 1960s and 1970s, decades-long claims that aliens from the planet Ummo were communicating with persons on Earth)

Pleiadians (one-armed Swiss farmer Billy Meier)

Nazi flying saucers (Nick Cook) - NAZI flying saucers "Vril", "Haunebu", NAZI bases in Antarctica and on the Moon . Avrocar and its descendants "military flying saucers" or "real world flying saucers" being responsible for UFO sightings, see fake flying saucers. More fantasy at U.S. built flying wing disc aircraft? (1946 - 1967)


Youtube videos of UFO over Haiti and Dominican Republic -"UFOs" over Haiti and Dominican Republic, created by "Barzolff", a professional animator, using Vue6 software (various types, most imaginative is the "Flying Spaghetti Monster"-type UFO):

WTC helicopter UFO video (SciFi channel promo) - Video footage of UFO "buzzing" helicopter near WTC (*not* the case on 9/11), is simply an ADMITTED computer-graphics (CGI) promotional commercial clip for Sci-Fi channel! Other telltale signs would be that the "UFO" leaves a contrail. Read email by actress Barbara Sicuranza who played in it

California / Raji drones (May/Jun-2007) and followup Isaac's CARET Program and Extra-Terrestrial Technology (Jun-2007) - "California drones, a/k/a "Chad drone" and "Raji drone" photos. These surfaced via C2C by Mrs Linda Moulton Howe (who has did good work on cattle mutilations in the 1970s, but seems to have lost critical faculties in recent years, falling for one hoax after another)

Thursday, April 14, 2011


On Thursday I decided to do a little speed session. The weather was a little cold and windy. But I felt good and confident. I started with 20 minutes warm up easy run. Then I measured a distance of 400 meters in the bike path.  Speed session: 1:32(69);1:35(57);1:29(65);1:33(61);1:30(67);1:34(61);1:31(70);1:32(61);1:31;18 minutes cool down. (Rest/Easy jog)  It is difficult to run even splits because of the traffic and change of terrain in the bike path. You never know when someone is going to walk or block your way. The slowest reps were against the wind because I was running out and back. By GoogEarth ruler measurements I ran 465 meters for each fast repetition. Well, I don't know how accurate these measurements are. Total run time: 63 minutes.

On Wednesday I had a day off. My right quad was sore and painful. Better back off.

On Tuesday I did four times the Oakwood Valley loop and headed back home. Good run. My legs felt good. This loop was only 1.3 miles mostly rolling. I am recovering well from the Sunday's race. I would like to do a speed session this week, probably on Thursday. The weather has been really different this month. A mix of cold, wind, and rain. Very unpredictable. Total run time: 62 minutes.

On Monday I ran an easy recovery run. My legs are feeling good. I am not tired as I expected to be. I ran the bike path out and back and headed back home. It has been a weird weather this year. Usually I don't race at this time of the year at all. The pollen in the air causes me some horrible allergies. This year somehow has been a little different. I might have a couple more races before the fall. Total run time: 41 minutes.
