At most, it is a reliable source of advice for women who want to improve their chances with the opposite sex.
I spent about a year dating almost exclusively women older than myself.
Their words carry more weight because they have experienced what they are talking about. All of this allows for an openness that makes a date or casual interaction much more enjoyable.
The male advantage in general intelligence does not emerge until after puberty, because girls mature faster than boys.
Since the time when I dated older women (a couple years ago now), I've found one, maybe two girls younger than me that I was attracted to and able to connect with - out of all the women I've encountered or even dated.
Older women are simply more interesting to be around.
Older women should be cynical about younger men who claim they want to date seriously, or remain silent about commitment. Women peak somewhere in their twenties for external attractiveness. In general, men disagree about the age at which women "peak" - partially because it varies depending on the woman and partially because guys have different taste.
Here’s a perfect demonstration, using data from the National Child Development Study (NCDS) in the United Kingdom.
However, when it came time to cut it off or have a relationship, I cut it off.
Reconsidering my motivations for those decisions now, I recognize one that dominated the others: despite my attraction for those women at the time, I didn't want to look around myself ten years later and see a hotter, younger girl - closer to my own age - and think "I could have been with a girl like that instead." When my wife starts aging, I want the other girls I could have had (i.e.
those in my age-range) to be aging with her, so that I won't be constantly reminded of the sacrifice I made to be with her - even if it was one I know was worth it.
The grass is already always greener on the other side, and a man doesn't need an age disparity contributing to that effect when his woman starts losing her initial shine.
