Basketball?

I played 3-on-3 half-court basketball for about two hours on Saturday with people who were either more fit or younger than me, or both.

I held up pretty well. I only got seriously winded once, while covering the most athletic player.

Right shoulder is a little more sore than I'd like, and I dove once & fell once on my still-sore hands, but it wasn't a real problem. Hip flexors, hamstrings, and neck are a little sore from looking up and jumping, but that's to be expected.

My knees did not hurt at all. None. Not eating grain as a way to fight inflammation works for me. Period.
