well Ted, men are wearing more baseball caps now than in any other time in history (at least around here in Ohio). I was basing my observations on 10 years of quizzing men who came into the health food places I've worked. Not a science study by any means, purely anecdotal evidence to be sure, but enough to convince me. BTW I've never worn hats. I consider my long flowing locks a "free hat" LOL
Yes, hormones can alter the hairline ( men can get way too much testosterone from overeating red meat,BTW. Hormones routinely fed to animals tp fatten them up remain in the meat, even when cooked.)
Y'know what guys....I'm bowing out of this discussion gracefully. Bon appetite.
