I have seen it more and more of recent, this includes my trouble with such a subject. In the modern world we are so indoctrinated with de-attached social assumption that to get to normal human congress takes a visual middle ground, for the guys, the body of an athlete.
Its a shame that I could only have ladies talk to me with the hell of extreme work. Based on this I asked several girls (quite a few more than I realise) and they said something about women having to wear make-up and dress nice, not funny but that doesn't hurt.
(quick rant now) I hear a lot of ladies also say they look for personality but they forget how they found out, they were attracted by a look or assumption based on look. I test this by wearing different types of clothes (usually more relaxed in aesthetic such as sweat pants for example) or covering my body shape, the results are instant and disheartening. Even though I act and say the same things, the image plays a massive role even with the most intelligent of ladies.
This may sound very bitter but I have been several body types and through them all my intelligence had no genuine factor, it was the look and function that prevailed every time in all level of opposite sex interaction. As well I have tried different guises to test my theories, the only one to get positive result was acting either nasty or cocky, in this world the nice guy does finish last or not at all.
Those boys in the film told of their ridicule which drove them to such things, this is so wide spread, I'm sure several of the fitter guys on here have either had ridicule or a negativity to drive that need to change.
As the world get more and more obsessed with de-attachment from reality this problem will worsen in my opinion.
