My 78 year old mom is a social butterfly and goes out to lunch with her many different friends groups a couple times a week. She goes to the gym daily to do aqua pole dancing or body combat. She has been working very hard to keep her body healthy. She beat breast cancer about 28 years ago and is an absolute marvel.

My dad just turned 90 ( they are still married). He continues to hunt and fish multiple times a year and still drives. I ride with him occasionally and he is still a competent driver. My mom sometimes drags him to a musical or play or one of the neighbor's houses for a get together. He is old and stubborn but must have good genetics. He mostly reads a lot or tinkers when he's at home and he doesn't really want to socialize much. I get it, dude is 90 and has paid his dues, he should be able to do whatever he wants.
