David Thompson: When I got past 60 — definitely at age 61, maybe at 62 — I could still dunk when I wanted to. But I’ve had a knee replacement, and I’m probably going to need another one. So I don’t try to dunk now. The doctors have told me not to attempt it, and I’m trying to preserve whatever I’ve got left. (Pauses) Actually, I probably could still dunk if I wanted to. But I don’t want to chance it.
