Why do people care? I knew a couple in which the man was 70-something and the woman 20-something. She was extremely intelligent, with a high-powered job, he was an impecunious but successful artist with the personality of someone college age. He was more experienced, but she was smarter. Except for the oddity of the age gap, they were psychologically perfect for each other, amused each other greatly, and had a wonderful time together. Eventually they broke up, but so do most couples. As an older guy, I had relationships with women as much as 12 years younger than I am, and as a younger guy, with women as much as 18 years older than I was.
