I think Salvo82 has it generally right. But there is a cohort from whom you might draw.-older, successful men. The best-known example is Margaret Thatcher. She married an older, very successful businessman. There was a prominent elected official in Philadelphia some years ago who married a prominent media personality who was at least 20 years older. People live longer. A man in his 70’s can be more vigorous than some 40 years old men I know.
