Girls who marry older men besides money, why?

At a swim meet and there is a hottie with an older dude. Fifteen to 20 years difference in years is cool when he is early 40s and still able to keep up but he soon hits 50s and in his 60s his kids look like his grandkids and people wonder if you are his daughter. I get that he had money and experience and knew how to treat a lady but time is a bitch that respects no one. People don't think when they get married in general but when someone is 15-20 older just remember that when he is in his 70s you're in your 50s. Big difference in stages of life. I just wanted to warn the OT 10s on here in case a rich baller was putting the moves on you.
