From the article, as to 8 glasses of water a day: There is no medical evidence to suggest that you need that much water,"This is a great relief. If it is not a myth itself, and remains true as long as I live  Cause it was said previously, that coffee and black tea don't count, and there was no mention of fruits&vegetables. Are you saying that all of the above are untrue. I don't know if that makes me happy or sad. All my natural born days, I have been told to turn a light on or you'll destroy your eyesight. ...and that water thing well I will have you know as hard as I try ...it just never seems to happen  and are you positive about that Turkey thing, are you really sure? The good news is that I won't have to make sure my hair is cut before I die now. LOL I am telling you my generation heard this stuff all the time and we truly believe it. That 10% of the brain thing always drove me nuts. People believed and accepted that so readily, yet you never heard a doctor tell a head trauma victim "The bad news is that 70% of your brain was destroyed, the good news none of it was the 10% you use so its no real loss!" My doctor never believed any of those things! Although, mostly it's not that these are False, so much as that they over simplify a a complex situation. For instance, it is important to stay hydrated, but how much you need to drink to do that varries depending on the person and their lifestyle. For instance I'm a big guy, I drink 10 cups of coffee a day (a diuretic) and am very active all day long, so I usually drink about a gallon of water a day. But that would be crazy for other people. I also try to use as little of my brain as possible. I'm currently down to 1.7% Hmmm, what hope is there for me, i don't drink water at all, on any day, just in tea and other foodstuffs...am i doomed to shrivel up into a prune...well you judge. The hair one has a little truth in it, in that you and your hair are like a farmers land in that a cetain amount of hair folacles lie fallow, but in order for that to happen the hair has to die first, if you cut it it will grow back immediately and if you continue after a short while all the hair folacles will be "in use", hence the appearance that your hair is thicker. Myth: Mobile phones are dangerous in hospitals. Just for the sake of being complete, there's #7. Regarding that one, I can see it's point for the purpose of consultation, though I'd still be hesitant of anyone on the phone while giving me an I.V. or whatever kind of procedure...similar to how driving while on the phone (even hands-free) reduces focus and concentration. Actually a study shows that people under the age of 18 are seriously distracted even by a hands-free unit. This is because the human brain, when we are young, is designed to acquire information extremely quickly by focusing on one thing at a time. As we get older our brain becomes more flexible and we become better at multi-tasking. This is also why children and teenagers are so easily distracted from everything else. Once again, the reason many of these things are myths is because they are true for SOME people, but not ALL people. Perhaps that study did conclude that, but I don't know it has been settled as fact. There's plenty of others that say otherwise. Quoting from a Webmd article: This increase in crash risk associated with cell phone use was found regardless of the sex or age of the driver.Or this study contradicts the multi-tasking aspect. I guess that's one of the cool things about science...one study doesn't mean anything until others can replicate the results. You're right though; we're all different. I just know from my own exper... Well, the reason I like this study (still looking for clip, which was somewhere around here, I swear!) is that it was not directly researching driving concentration, but researching the way our brains worked. If I just do a study on driving, without considering the diferent kinds of people involved, and why they were the way they are, I'm stabbing in the dark. This observes a change in the thought process of the brain from one age to another, explaining why teenagers has such short attention spans and can't focus on more than one thing at a time, while older adults can multi-task much better. This is then useful to cross-apply to the data on cell-phone risks, and shed new light on the rese... Another great myth is that the human body temperature should be 98 degrees. This was a ridiculously small study, conducted in (I've been told) Nebraska, because that was the middle of the US. (Could be urban legend.) Thus you have people like me, who run around 96 degrees, and Yossarian, who runs at 101. Doctors would never diagnose me with a fever because they always figured I was normal temperature, not realizing that 98 for me is like 100 for someone else. |
