Until they open their mouths. Seriously. I have seen 10/10 bodies lose all advantage in one sentence. I have seen ugly women that after a few minutes talking with I would spend the night with without problem.
You fantasize about perfect bodies until you get to fuck one. Then you realize sensuality is something else altogether.
And once you reach 35, you realize how sexy it is for a girl to be financially independent...
You present this as though it supports your point, that you "cannot cheat biology with feminism". To me it's actually more evidence that there is this complicated system running, with multiple feedback loops on multiple levels.
I'm not saying that there is nothing here in terms of biology, of course there is, but the relationship between biology and culture is subtle and complicated. Little in life (maybe nothing) is as pure and simple as many people seem think this issue is.
Men are attracted to fit, young females. Maybe because women in the past tended to pick not the youngest but the most powerful (in this particular social circle?). Thus humans learned that both parties are ok with age difference.
It seems a bit gross, a 70yo with a 25yo girl. It happens less often now (a wild guess), so maybe social pressure helps a little bit. But i believe that men still prefer fitness over education in women. Not 100% of the time, not in edge cases, but in general. Even in the press, a guy is more often smart, funny, successful and a girl is beautiful, elegant, and so on. Not always, but more often than not.
