Why? Body hair saves you a bundle on sunscreen.
When I was kid, we were in Key West in a little store. A guy comes walking in to buy a paper looking like the original Dos Equis "Most Interesting Man In the World" sporting a white captain's, a pair of Speedo's, and flip-flops. He had the same reddish-brown curly mat of hair going from the base of his neck to the tops of his feet, except where his barber shaved it under and around his beard and the hair on his head. It was the most amazing thing I've ever seen in my life.
I tried to emulate him, but not even Rogaine could stimulate my ample body hair in adulthood to max out like that.
No wonder he lived in Key West? With assets like that you would want live in a place where you could show them off year round.
