That does not make a lick of sense at all. Not to mention, incredibly ignorant. If you're referring to sexual prowess, a woman is at her peak around 32 and a man is very much past his peak after 21 years old. So really, it's the young guy at 25 who needs to keep up with that 32 year old.
If we're talking in general, women around that age can still keep up with the trends and popular things in life, regardless of income. Women, like men, can have fun and do it big at that age. I don't know where the hell you get that idea from, but really...you need to actually speak to women more before you make another baseless assumption.
