What's something you did once but won't do again?

Play paintball.

I started playing back in the 80’s when I was in college and everybody used paint guns that could only hold about 15 rounds, and fired one at a time.

I’m way too old to run around in the woods like I did 40 years ago, and the game has completely changed as well. People have guns that can hold hundreds of paintballs and shoot incredibly fast, so the whole strategy is unlike it was. I just don’t find modern paintball enjoyable at all.
