What a stud.
But seriously, if you do live long and healthy as a guy, you have the pick of the litter every day in the assisted living facility. Ratio is probably 10:1. It has been a tabu but old people are actually reasonably active sexually if health does allow it. And why not. Old women are probably attractive to us guys, once we are there too.
Also, nobody noticed that she is 18 years younger than him. That probably helps. I know it would for us mid-aged guys ... n-18.
