I think the ideal formula for men is to select women half their age + 7 years.
It is pretty standard for men to date younger women. Men often get richer & more confident as they get older, which makes them more attractive as mates (imagine that??).
I will also say that [native] Asian women routinely look 10-15 years younger than they really are. In contrast, most modern American women look 5 years older than they really are.
Sounds like Yann Moix has discovered Viagra. Unless he is rich no 25 year old will look at him.
