Really good idea....

So I was just thinking about this the other day... it has been more or less agreed upon in my informal poll of my friends from college, that the men we went to college with look worse now than they did then, and the women look better. We used to think this was because the men used to play sports and drink excessively. But now they just drink excessively. Anyway, so my idea what that this phenomenon has more to do with sexual peak. Could it be nature's way of procreating us? Making men the best-looking at 18 and giving women until 35 to look their darn best? Is this even true? It was just an idea.
