A younger woman is still hoping the guy might have one on him. An older woman is a cheaper date. A younger woman will cost you 12 beers, but an older woman will sleep with you after a cup of a herbal tea. An older woman can wear bright red lipstick during the day without looking like she just had an adventure inside a jam jar. This is not true of younger women or drag queens.
Older women can run faster because they're always wearing sensible shoes.
An older woman is almost always already attached to someone, so there's no need to develop a phobia about committing to her. The last thing she needs in her life is another clingy, whiny, dependent man. Older women are more honest. An older woman will tell you that you are an asshole if you're acting like one. A young woman will say nothing, just in case it means you might break up with her.
