FWIW this is why I've adopted Curling after playing hockey for a decade. It is an incredibly skillful and physical game and yet you see 80 year olds at the rink playing it. You can get good at it and be good for a long long time. You don't get too old.
Also the beauty of golf. You can enjoy it until your 70s, some even older. You can do outings with several generations. Has shorter tees for younger, older, ladies if they want to use the. It also has a legitimate handicap system so everyone can compete.
I also really love fishing, mostly for different reasons, but it's multi generational too of course.
