The younger women that these older men pick on that show always flake off after the first date, leaving the older men to wonder why. The "older man/younger woman" saying is a myth.
I know several guys over forty, almost in their fifties, who are still waiting for that unsual younger woman to come along and marry them. Why? Because they want to have children.
Another subject would be the unsual young woman who marries a much older guy while in her twenties, only to divorce him in her late twenties to early thirties, and find that now that she is in her thirties, she would much rather marry someone her own age, but can't find a guy her own age to marry her, because the men her age want marry someone in their twenties. Meaning, "women who waste their youth on older men".
