A person's outer looks and attractiveness have always been important and unfortunately baldness really does erode most people's looks. It's really that simple and that's why most of us are here. We all care deeply about the way we look and the vast majority of men will always look better with hair than without hair, some to a very substantial degree. With regards to Patrick Stewart, I just never thought he looked that good. He just looks old. It not impossible to look better as a bald man than with hair (The Rock looks better bald), but it really is the exception and not the norm.
The media makes fun of baldness because it is an easy target. If they made fun of a person's race or gender, they would be in a massive heap of trouble (and rightfully so). Yet it is perfectly acceptable to poke fun at baldness (and it is such a noticeable characteristic), and that is why they do it. Plus, commercials today are geared for complete morons. One is more stupid than the next. Whenever I watch TV, I ALWAYS mute the commercials. That's why I never saw this Ace commercial before. Because my TV was muted and I wasn't paying attention.
Whatevr, you're totally right about the genetic sensitivity part. A couple of weeks ago, I was lifting at this huge powerlifters gym on a weekly pass and there were guys there who were so roided up that it's a wonder their livers are not like concrete. Yet some of them still had full heads of hair whereas if guys like us (prone to hair loss) roided as much as these guys, it would wreak absolute devastation on our hair.
