Shouldn't that be the other way around? Namely: 35 for women and 40 for men? After all, biology is destiny. The author has apparently never heard the expression "shelf-life."
A man could reasonably argue that, stereotypically, going to college (and studying seriously), making a career, and accumulating the necessary wealth to support a family have delayed his entrance to the "market."
A woman who has waited until menopause has (almost) set in, however, obviously has "issues," since the delay will have significantly degraded one of her primary functions.
