I'm 39 and none of my friends in my age range seem 'lost'.
There could only be two reasons:
1) Job market. Men define themselves to a degree, and women certainly judge them on, their job. And since the recent recession hit men the hardest, and they are having the hardest time making up lost time, that could be a reason. Of course feminists don't care about men, so this is underreported, they just want to bitch about the non-existent pay gap.
2) The marriage market. Most women are unmarriageable. The fat ones are completely off the radar, and finding an attractive woman who is also tolerable to be around is far more difficult than it should be. The feminist mantra of "act however you want and no one can judge you" is creating a lot of cat ladies.
Men can fill that void through camaraderie with other men, and sex with younger women. As I've mentioned, friends my age and even a few years older have no problem meeting younger women. Sure, some guys I know are happily married to good women. But theirs is a marriage based on compromise. I'd say most of us would want to settle down, but we're unwilling to do so under what is considered the terms of marriage these days, which is whatever a woman wants it to be.
So articles like this, and the media in general, likes to pile on men from an emotional point of view. But the facts are that the job market has changed, and the sexual market has changed. As much as they want to push the notion of being a fat whale is just 'curvy', or that men should date some 'age appropriate' barren ghoul, men are going to naturally resist this.
So it's not 'lost', rather that our voice isn't heard, certainly not on an equal platform as women, especially feminists. Note the plethora of articles written by obese young women and fat middle-aged spinsters about their issues. As has been said, years ago they'd be put in a mental institution, now they are given a platform. If a man said such things, he'd be told to go to the gym and work on his skills. Women should be held to the same standards. THAT would be equality.
