truth or myth?(post interesting stuff about the human body!)

Is it through that we breathe (unconsciously) through one nostril at a time and in rythmn?

My little brother just told me this and I find it hard to believe him.

Is it true that a beanstalk grows out of one's ears if he eats beans? Just kidding.

My real question. Is it true that reading in the dark gradually make your vision blurry?

My friend doctor says that vision is inherited from our parents. My parents say otherwise, that poor vision is acquired by always reading in the dark.

@vanille: I'm pretty sure thats false, the nostrils connect in the nasal cavity so it would be impossible to do....unless there was some tyep of flap that covered each nostril, and there isn't.

@jeromep: Vison is inherited from our parents but things like reading in the dark and help your eye get worse faster. Usually eyes will get progressively wose as we age, but doing things like reaing in the dark or sitting in front of computer all day can accelerate the process.

This is more of a did you know than a question, but it's pretty cool:

-After a head is decapitated from a body, it continues to function for a few seconds. An experiment was done back when they were still decapitating people by guillotine to test this. Some scientists approached a convicted murderer and asked him to, after his head was cut off, blink a specified pattern. Sure enough, right after his head landed in the basket, he blinked the pattern, then died. No one's sure about the pain idea, since with no wind the heads can't talk, but it would seem it must not be too bad (either due to shock or simply a severed nervous system) because he was able to perform the pattern, which would be hard to do while wincing.

I heard that your stomach's lining is so corrosive that it digests itself every few hours Shocked

an adult has 206 bones in his body, you don't lose the "baby-bones"
they just grow together, bestr example: a babies head. you always have to be carefull with babyheads, 'cause it still excist out of two parts that need to grwon together, and to much pressure on a babies head kan split those parts and kill the baby.

and did you know that when you would put all your veins in one long line, you could go around the world 4and a half times!

That stomach thing has a bit of truth in it, in that the stomach's digestive lining replaces itself every so often (although I don't think it's every few hours). That guillotine anecdote is peculiar, though.

As a child, I was told that when white spots start appearing on your fingernails, it means you need to eat more vegetables. Of course, parents probably tell their children that they need to eat more vegetables because the sky is blue, BUT... I was wondering, does anyone know what DOES cause those spots on your fingernails? I still get them once in a while, no matter how many vegetables I eat.

ALSO... extremely small red spots on the upper arms; is it a liver problem, being out in the cold too long, or what...?

Ah, thanks! I do tend to smack into alot of things, being clumsy and all... so that's where those white marks come from.

And about little boys touching themselves... there's actually a standard behavior among very young children (male and female) called infantile masturbation. Might be worth a search on Google. Strange, eh?

Another 'Did You Know': Apparently the surface area of the average human lungs, if stretched out, cover the area of a tennis court. Apparently.
