(NaturalNews) “We only use ten percent of our brains.” We all grew up hearing that, and many of us still take it for granted. Didn’t you ever wonder why we have so much unused gray matter upstairs? In fact, that popular belief (current as early as 1907) was put to rest a long time ago. Although certain functions may be confined to certain areas of the brain, PET and MRI scans show the we use the entirety of our brain, all the time. Constant repetition makes the myth seem real, but it’s just not so, according to a recent article in the British Medical Journal.
The 10% belief is only one of many old wives’ tales that the Journal discounts. Will shaving make your hair grow back faster and coarser? Gosh, seems so sometimes. But that’s an illusion. Normally hair grows to a fine taper, but shaving cuts it off at an angle, making it seem coarser. It will grow back at its own speed and thickness; shaving has no effect on it.
Then what about that story of hair and fingernails continuing to grow on corpses? Oh, please don’t destroy that wonderfully ghoulish myth! But myth it is. According to the experts, what happens is that after death the skin dries and shrinks, giving the appearance that hair and fingernails have lengthened. Aww, there goes the "gasp" effect in horror movies!
Are mobile phones really dangerous in hospitals? At one time it was possible for them to interfere with the operation of medical equipment, but despite widespread concerns that this might be happening, it’s no longer true (do turn your phone off when you board a plane, though).
Do we really need eight glasses of water a day? Researchers Aaron Carroll and Rachel Vreeman don’t think so. They claim there’s no scientific basis for such a claim. Still, I like to keep my kidneys in good working order and all toxins flushed out.
Did your mom scold you for reading in dim light? Were you threatened with a dire fate, like blindness? Relax. You might blink more or have trouble focusing, but experts say that reading in low light will do no permanent damage. You know your mom meant well, though.
Six old wives’ tales that many old wives, and husbands (let’s be fair), have kept alive through the years... all discredited. All untrue. That leaves only one, the seasonal one: the story of the sleep-inducing turkey. You’ve heard this one, I’m sure. Conventional wisdom has it that the amino acid tryptophan in turkey makes you drowsy. It’s true, isn’t it? Isn’t it? I mean, everyone wants a nap after that turkey dinner!
Turkey does indeed contain tryptophan - but no more than chicken or ground beef. What really makes the uncles doze off after dinner? Too much of everything - turkey, dressing, peas, pies, and wine. While the body works on the intricate process of digestion, the brain goes on recess.
Well, not exactly. It’s still busy overseeing all those bodily functions and managing your dreams, all 100 per cent of it.
