Simple, young women are tired of dealing with the baggage that most young men present. More often then not, young men aren't ready to commit but might give the impression they are just to keep the woman happy. And then the man usually says he needs to test the field and that he's not ready to settle down. Older men have already been through that road and prefer stability. It's not to say that an older is better are presents less challenges, but the ones that he does offer are less of a hassle then what the younger man has to offer. Just my two cents.
