My kid brother was born when I was 15 so I remember it well. He came out with thick black hair on his shoulders and back. The doc said it happens sometimes and it's not a problem but we were all a little worried. He didn't cry at all for 6 weeks either. But after 6 weeks the hair fell out and he was fine.Never had any hair on my back. Had a BIL who looked like a neanderthal with thick hair on his front, back, neck, shoulders, arms and legs.
He reminded me of this dude.

LOL, no it's not a good look.
I think some of the neanderthals survived extinction and blended into society. It's the only explanation I have for how things are in the world today.
