Ask an American Indian. Better yet go look at them.
I was a blond, blue eyed boy with no chest hair. When I was about 10-12 years old, I had 1 hair in my chest about 1 1/2 inch long. Dad was cutting my hair and in his clean up effort, brushed me off and snatched my chest hair and it was gone.....I protested loudly, we all laughed, and it never grew back.....oh well...I'm 73 and still without chest hair!!
