Nobody my age will do that stuff with me, so I don't do it. I think I could snow ski and water ski just fine. Perhaps not exactly as "fine" as when I was 26 but I think the knees would do it and muscle memory. I'm only 65.
I have some college buddies who I gather with occasionally. we're talking of a 2023 TripFest. Maybe Belize again. Now that I am actually certified.
