I have a theory that as you age your hair moves slowly down from the top of your head. That would explain why some men are bald on top, and why ear and nose hair increases with age. Of course (conveniently fitting in with the theory) you wouldn't grow hair in non-hairy spots (forehead?), but hair would increase in hair-prone spots.
I've also always thought it is lucky our pubic hair falls out naturally or we'd all have long pubic beards.
