<p>My job requires long periods of computer screen use. I have good eyesight (20/15) and don't wear glasses, but I definitely notice my eyes feeling fatigued at the end of the day. Sometimes when I'm short on sleep, I have trouble focusing or see slightly blurred vision.</p>

<p>The received wisdom seems to be that bending forward for prolonged periods of time is bad for the back. Fine. However, the "received wisdom" has been, for a long time now, that sitting bolt upright is the best posture for the back. However, <a href="http://news.bbc.co.uk/1/hi/6187080.stm">a study</a> actually concluded that much more of a reclined posture was actually better for the back:</p>

<p>Cellular phones are taking ever increasing part in our lives, and I keep hearing people saying they are harmful to our health.</p>
<p>Are there any scientific researches so far proving or disproving those claims?</p>
<p>I found couple of semi-scientific articles:</p>
<ol>
<li><p><a href="http://www.mayoclinic.org/healthy-lifestyle/adult-health/expert-answers/cell-phones-and-cancer/faq-20057798">Is there any link between cellphones and cancer?</a> which says: </p>
<blockquote>
<p>The possible connection between cellphones and cancer is controversial. Many years' worth of studies on cellphones and cancer have yielded conflicting results<br>
...<br>
In one study that followed more than 420,000 cellphone users over a 20-year period, researchers found no evidence of a link between cellphones and brain tumors<br>
...<br>
Another recent study suggested a possible increased risk of glioma — a specific type of brain tumor — for the heaviest cellphone users, but no increase in brain tumor risk overall.</p>
</blockquote></li>
<li><p><a href="http://www.medscape.com/viewarticle/834888">Long-term Cell Phone Use Linked to Brain Tumor Risk</a> which says: </p>
<blockquote>
<p>Long-term use of both mobile and cordless phones is associated with an increased risk for glioma, the most common type of brain tumor, the latest research on the subject concludes.<br>
The new study shows that the risk for glioma was tripled among those using a wireless phone for more than 25 years and that the risk was also greater for those who had started using mobile or cordless phones before age 20 years.</p>
</blockquote></li>
</ol>
<p>Though the second appears to conclude direct health risk, I'm pretty sure it's not yet any hard proof otherwise we would have seen huge lawsuits being filed all over the place.</p>

<p>I regularly donate blood, however, I am curious as to what happens to my blood after I donate. Obviously some of it will go to people in emergency medical situations, as I intend. However, I have never heard of situations where someone died because we didn't have blood to donate to them; which makes it sound as if we don't have a blood deficit. That in turn makes me wonder what the excess blood is used for.</p>
<p>So I have two related questions. First, do we ever <em>have</em> a blood deficit, situations where someone who could have been saved in a hospital dies because there wasn't blood to treat them? Or specifically situations like that caused by a lack of donors, not some logistical issue getting it where it needs to be. I have had the red cross call me and tell me that they have a 'deficit' many times, but frankly I hear it so often it leaves me questioning their definition of deficit. How often do we really run out?</p>
<p>Related, if we don't run a deficit then what happens to my excess blood? I assume that some blood is regularly thrown out, but they figure it's better to have extra and risk it expiring then to run out during an emergency. However, if we have a high enough surplus do they do something else with it? For instance is it used for medical research? If we had say 5% fewer donors would it be our medical research which suffered, but not patients in the hospital?</p>
<p>I will continue donating blood regardless of the answer here. I'm simply curious as to the result. Well that and it informs this discussion: <a href="https://skeptics.stackexchange.com/questions/28118/is-the-red-cross-policy-of-refusing-donation-from-homosexual-men-justified-by-in">https://skeptics.stackexchange.com/questions/28118/is-the-red-cross-policy-of-refusing-donation-from-homosexual-men-justified-by-in</a></p>

<p><code>(Nd / (Nd + Nr)) * 100 = 41%</code></p>

<p>I'm sure this question is asked a lot. I asked it of two different doctors myself recently, one of them a diabetes specialist. They both said that causing too much sugar did increase the risk. Neither offered any actual evidence. The specialist gave a rather strange reason, which now escapes me.</p>
<p>This idea has inherent plausibility, because eating a lot of sugar could be assumed to stress the body mechanisms that keep sugar level in the blood under control. Too much stress could cause these mechanisms to break down. This is, however, not the reason the specialist gave.</p>
<p>A confounding factor could be that eating too much sugar might cause weight gain, which might increase the risk of diabetes for different reasons.</p>

<p>One of the most often-cited facts about human life, compared to those of other animals, is that the main reason we live so much longer is modern medicine. Because we can treat illnesses that would previously affect lifespan, we are far more likely to live greatly extended lifespans. However, this leads to two possible (conflicting) logical conclusions:</p>
<ol>
<li>People who by chance didn't get deadly diseases before modern medicine would live as long as people today, meaning the ability for any <em>individual</em> to survive ninety or more years, far longer than nearly all animals, is unrelated to modern medicine.</li>
<li>Every illness one experiences weakens the body in some way, robbing it of future years. This would mean the role of modern medicine in extending lifespan is treating these illnesses to prevent the gradual reduction in lifespan.</li>
</ol>
<p>If the first is true, then lifespan itself isn't influenced by modern medicine unless it prevents death as the direct result of a disease, and only <em>average</em> lifespan is affected. In other words, if nine in ten dies at age thirty due to a deadly disease, and one in ten dies at age eighty by avoiding disease, the average life expectancy is thirty five, even though an individual could by living an extremely careful life survive to reach eighty.</p>
<p>If the second is true, then short periods of non-deadly illnesses experienced by everyone each shorten life expectancy by a tiny amount, together decreasing <em>everyone's</em> lifespan to the same thirty five, rather than the effect being a result of averages.</p>
<p><strong>So does each illness shorten lifespan, or is it only a result of averages that lifespan was so low pre-modern medicine, and humans always had the capacity for exceptionally-long lives?</strong></p>

<p>I have read several web pages that mention the potential benefits of sleeping without a pillow.</p>
<p>Examples:</p>
<p><a href="http://www.newhealthadvisor.com/Sleeping-Without-a-Pillow.html" rel="noreferrer">http://www.newhealthadvisor.com/Sleeping-Without-a-Pillow.html</a></p>
<blockquote>
<p>Is Sleeping Without a Pillow a Good Choice? Yes, it is. Not only will sleeping with no pillow save your money, but it will also lead to less neck, back, and shoulder pain, higher quality sleep, and even fewer wrinkles! When you were a child, you could fall asleep anywhere without a pillow. The body is resilient and adaptable when we're young. Even as we age, our body, including heads and necks, is able to rest comfortably without the support of a pillow.</p>
</blockquote>
<p><a href="http://www.snoringmouthpiece-reviews.com/sleep-without-pillow/" rel="noreferrer">http://www.snoringmouthpiece-reviews.com/sleep-without-pillow/</a></p>
<blockquote>
<p>While sleeping with or without a pillow is a personal preference, there are some medical experts that believe there are real benefits of sleeping without a pillow.</p>
<ul>
<li>Spinal benefits: Some argue that sleeping without a pillow is the healthiest method of sleeping as it greatly benefits the spine. Sleeping on your back without a pillow allows the spine to rest fully with the natural curves of the body. When you sleep with a thick pillow it can displace the spine.</li>
<li>Facial benefits: Others argue that sleeping without pillows can help reduce wrinkles and other often considered unappealing facial features. This can be attributed to the fact that the face is not being squished against a pillow.</li>
<li>Sleep benefits: Some argue that pillows interfere with quality sleep, especially when people use the wrong pillow. Sleeping without a pillow helps ensure quality sleep because the body is allowed to be at a normal level and not elevated like with a pillow.</li>
<li>Neck benefits: The people that believe sleeping without a pillow is best for you, argue that sleeping with a pillow can be the main source of shoulder and neck pain. It is still good to do stretches and use heat packs, but they say that the best way to alleviate neck pain is to sleep without a pillow.</li>
</ul>
</blockquote>

<p>I like coffee, but caffeine seems to 'wire' me much more extremely than most other people. I feel energized or even shaky after less than half a normal cup, and a whole 8 ounces will usually cause me to sweat or make my heart race uncomfortably. </p>
<p>Even decaffeinated coffee seems to have this effect, which seems strange to me (although I am aware that it still contains a small amount of caffeine). I typically drink green tea instead of coffee, since the effect is more mild.</p>
<p>Is this an indication that my body metabolizes caffeine faster (or slower?) than normal? What else can cause caffeine sensitivity?</p>
