I think it all depends on the person. Some older women are like most men, who go for the younger versions. I have known some men who prefer the older versions of women as well, not just older younger women either. Then you have those who are younger that go for the richer older person, for their wealth. That is all they see in the person.
I like to see long lives well lived, in peoples’ faces; and a great sense of humor - those lines that indicate that someone has smiled and laughed a lot.
