Assuming hetero coupling: I don’t know why a 27yo woman would want to be with a 40yo man if we’re strictly talking about biological fitness of offspring. Makes more sense for a 17yo and 20yo, but there are serious diminishing returns for a young woman the older the man gets based on the decline in sperm quality. The chances are that she ensures better offspring by being with someone in her age range +/- 3 years.

FYI, this is what men like this person sound like when they evaluate women. I am just doing the same thing back to such a man. If he thinks he’s a prime target for young women, he’s not.

Personally, I think evaluating people simply based on their ability to produce offspring is gross because you’re removing any consideration for them as a person. I feel icky having this conversation. There’s something wrong with conservative culture that makes them evaluate people like cattle.
