Wow. To generalize like that puts you on a very slippery slope. (Coming from a chick who is 43)
While I tend to agree with you that a lot of gals make bad decisions and continue to perpetuate them the older they get, for the most part, if you're meeting these women in nightclubs, that's where the problem is. Especially if they are 35 and still acting like they just turned 21.
I just think girls go through changes for the most part at very specific ages. 27-- they are starting to see 30 on the horizon; 30--some chicks embrace it, some get super drunk on their bday's trying to deny it; 34--sexual prime and with possible cougar tendencies;, 40--liberation!
(but then again, now I'm generalizing)
