A lady was complaining about the fact that we even have pubic and rectal hair. Well, I have a theory. Back in cave man days, the folks didn't wear underwear. They'd squat down by the fire or to gather berries and the hair was there to protect their precious parts. OK, so then why do we still have hair down there since we have evolved into such sophisticated creatures who aren't squatting by fires bare assed? It's obvious to me. So Mary Elizabeth can have something to do.
