Besides never being seen w/out a hat, another indication of a man going bald is the growth of some facial hair. Beards are as popular as ever, but when I see a young dude who is always in a hat and rocks a beard, I automatically assume he is bald. I mean it makes sense, grow some facial hair to offset the loss of hair up top. Regular Joe's and hockey fans (the sport, not the FA offshoot) like to go with the goatee or donut to compensate for hair loss. Skaters, being the hip bunch they are, recognize that goatees are lame and opt for the bushy beard. In fact, MJ and Reynolds are rare exceptions to the bald with beard trend. MJ did have a beard for a minute. But think about it, I know a ton of people who's beard status directly correlates to the rate of their hair loss. Judging by Windsor James new Grizzly Adams beard, I'd bet somethings happening under his hat.
And all the dudes that are saying it's no big deal going bald, or that it doesn't matter, obviously have full heads of hair.
