Hmm... Should I get into dumb VR games like BeatSaber? I want to do something that feels like intense fighting. Biking fast enough it's satisfying is too dangerous. Maybe unrealistic point based karate would be fun. I tried fencing once but it was shockingly lame. I'd join a dodgeball league but there aren't any, everyone wants to do like baseball and volleyball. Hmmmm. I wonder if paintball would be fun or tedious, I could see it going either way.
you know that 99% of martial arts is practicing the same punch 1000 times by yourself, not finding random dudes to throw punches with? There's lots of intense fighting things you can do with only a punching bag. The risk is basically zero unless you try to 1v1 somebody.
also slow mountain biking is awesome.
