Older Men-Younger Women Romances Good for Longevity of Human Race

Younger women being attracted to older men is biologically based:

Older men who shack up with much younger women keep the Grim Reaper at bay for the human population and extend our species' lifespan, new research claims. . . .

As relationships seem to be less motivated to produce children over time, there might be a correlation with a reduction in the average age between men and women. I wonder whether there is empirical evidence that men search for other mates when the women that they are with are no longer able to have children.

What is not noted if that the same would hold for females. Older females should reproduce and marry (whatever) male age group. This might actually have a larger effect on longevity because, say, by 40, a lot of women cannot have babies because of either bad eggs and/or because of health problems. So the women capable of having babies post-40 are the ones with healthier genes (and genes for longeivity).

Does it occur that the reason that women marry older men is because EVEN THOUGH the women are more attracted to younger men, the older men might have more wealth/higher income and are more likely to be stable emotionally? So the 24-year old woman in the U.S. who marries a 28-year-old man rather than a 20-year-old is likely to be able to start have babies earlier. It is not particularly impressive that he made it all the way to age 28 even though it makes some slight difference in weeding out the ones who committed suicide or died in a car crash at 21.

Also, demographics force many women to marry older men. There is just a tremendous surplus of women to men in the very highest age-groups, and those men like to pick the relatively younger (old) women, who also will take care of them when they age and die.
