The Hair Up There
I was wondering... why is baldness basically the same pattern for all balding men? It's the horseshoe-shaped line of hair that goes from the ears around the back of the head. Why doesn't it ever reverse itself, so that the hair goes around the forehead? Or the opposite, where there is just hair on the top and forehead but not around the sides and back? Or stripes, like Mr. T? Or just random splotches? I can't think of a good scientific reason for that pattern to be useful... if anything, it exposes the front and top of the head to dangerous sunlight. Anyone have info on this?
