You might call it "Poetic Justice" as the tables are turned on women starting in their mid to late 30's. When women are young (late teens to early 30's) they have men bending over backwards for them (buying them gifts, taking them on vacations, etc.). Then starting in their mid 30's, women start to lose their looks and their power they have over men.

Men on the other hand, have it difficult in the dating scene when they are young. For example, a guy in his 20's who is still living at home won't be able to attract too many women because he is still living at home and probably doesn't have a good paying job. Now fast forward to when this guy is older and in his 30's. He is out living on his own, maybe owns a home, has a nice car and a good paying job. Women who are in his age group (women in their 30's) want like heck to date him but wait he doesn't want to date them because he is interested in younger women only (women in their 20's).

Paybacks are a bitch! These women wouldn't give this guy the time of day when he was in his 20's, living at home, driving an older car and not making a lot of money. Now, these same women are all over him like flies on shit because he is successful. Well guess what, he is not interested in these women because they are not attractive anymore and he is only interested in young attractive women!
