Hair on your arm
Why, when it's cold outside, do our arm hair stand up? I mean, they seem to cover more skin when they're laying down. Does this make sense to anyone else?

it isnt the hair standing up but the pores that the hair come out of closing to prevent respiration, also known as breathing. yes, your skin breathes, so when its cold your pores close to prevent cold air from coming in those tiny pores that completely cover your skin.

it does make sense, but when your hair stands up it traps that sits next to your skin and creates a layer of insulation to warm you up
nah your hair on your arms dont really trap shit, you lose more heat through the pores.
there is too much open space to create an area for it to insulate and it just escapes b/c there isnt anything to hold the warm air there.

I thought it was a vestigial trait. Heat rises, so hairier animals' fur stands up to trap the most heat, ie it makes the hair layer as thick as possible so rising heat is bounced back. So human hair standing up is a vestigial trait because we've evolved away full body hair, but our hair still responds the same way.
Good luck, and good smoking
ya man, 100% correct
it feels good when theres weed world applications for my education
All very interesting theories. Although, I agree with tonebeats. "America's Most Blunted"

I shave my arms.
no, your a robot. don't lie man, we know :)
We discussed this in one of my classes, apparently it creates a small buffer zone to keep wind from rippen heat off your body as fast. I doubt this is the only reason but im pretty sure its one of them.
