Why do people have hair on their arms/legs??? And why does it only seem to grow on half your arm?
I expect that it is an adaptation. Here's an interesting article - http://en.wikipedia.org/wiki/HairPengwuino said:Why do people have hair on their arms/legs??? And why does it only seem to grow on half your arm?
Well, I don't know about your hypothesis :uhh: You'd have to have heavy long and curly hairs to notice anything! I can't imagine anyone having a split second warning that they are about to cut themselves with a knife because of the miserable little hairs on the top of your fingers. When you are already burning the hairs on your arms I'd think the heat of it would be a pretty good warning sign.hypatia said:Just about everywhere that a normal person would of had that split second warning they are about to hit something. And that would include heat{burns}, that quick little singe of hair that warns us to back off.
I don't suddenly get more cuts on my legs when I shave them, and competitive body-builders shave their entire bodies without winding up covered in cuts and scrapes.hypatia said:Monique, if you slightly touch the hairs on your arm, you feel it, no matter how short they are. And no I'm talking about cutting yourself with a knife, more like, brushing your leg near a ruff object..if you have hair on your leg..you get a warning.
And its not really my hypothesis, it what the guy told me when I noticed so many scars on him.
