Memory goes as you get older

In an interview published this morning by the NYT Senator Joe Lieberman shares this little story:

Is there anything that I did not ask you that you’d want to touch on? 
There are many things you did ask me that I shouldn’t have touched on. Here is a parting gift. There’s an older guy on the park bench, crying — tell me if you’ve heard this one. Finally a jogger stops, sees the guy sobbing. ‘‘What’s wrong?’’ ‘‘My wife of 48 years died, and I was very lonely. I went on JDate and met a younger Russian woman. We liked each other. So she’s moved in with me, and she’s wonderful. She’s attractive, she cooks well, she takes care of me and almost every night we have fabulous sex.’’ So the jogger says: ‘‘Well that’s a wonderful story. Why are you crying?’’ The old guy says, ‘‘I’m crying because I can’t remember where I live.’’
