well in most cases is based of other Vision some men look for young women while they are old , and women look for them as money bags :/
and some old women look for young men and the young men look for them as money bags :/
if the they dont have money no one will look at them   FACT
but in some cases and this is kind of rar , young men look for older women in specific details , for reasons he can't describe , its just how he like women
and same for women , and in this cases you will find both match and agree for that
in my case i like my woman same my age and even older up to 30 maybe , only in matching case
