I have had a few surf boards over the years, but never really got into it. I do still have 4 hang gliders. George Worthington was in his 60s when he set a hang gliding distance record in 1980 of over 105 miles and an altitude record of over 17,000 feet using a Mitchel B-10. One of the guys I used to hang glide with was in his 70s. Hang gliding is a lot less physically demanding than surfing.

I rented a surf board once, in Ocean City, NJ, when I was just a kid in the sixties. I got up once in 3 to 4 foot waves, and got cursed out by some guy for cutting him off. End of career.
