men who are older have always been attractive to women. the freshman girl in high school wants to date a guy who is a junior or senior, the senior wants to date a man in college, etc.
because what women value is different. they aren't looking for physical beauty, although that is a factor, but security, masculinity, intelligence, confidence, humor, maturity, etc. someone who takes care of business, someone she can rely on. older men appeal to younger women on an biological and intellectuall level. older men understand a womans needs and desires better than younger men.
the opposite statement cannot be made. men value physical beauty extremely high, they value a woman's womb so child bearing age women are always chosen over women who cannot have kids. we only consider other attributes once the beauty standard is met.
if a man is successful, fit, and dresses and grooms himself well, he will do very well with women and constantly be able to pull beautiful looking women far below him in age no matter how old he gets.
you posted examples of nothing but men who let themselves go, get fat, or abused drugs like crazy, or both
take a look at sean connery, jeff goldblum, etc. they had women in their 20's dripping and fiending well into their 70's. women find men with grey hair sexy so often there are even terms for it like silver fox, etc.
