Is it true that if you shave all your body hair you will reverse the aging process?

My friend has one armpit that he doesn't shave at all but he shaves the rest of his body completely, I asked him why he does this and he says that it's because if you shave your entire body you will reverse the aging process and start aging backwards towards a baby. I would love to be a teenager again! Does this actually work? Has anyone tried it?
