gollark: Also, you apparently didn't hide anyone else's faces. That's probably impressive, though? I mean, I don't have context for such numbers, but they seem big.
gollark: I checked on the internet™, and apparently there are something like 10 combat-sports places in [somewhat nearby city I go to school in]. I'm sort of wondering if there's some local history I've missed. [nearby city] is still something like 25 minutes to travel to from where I am, which is annoying, and there don't seem to be any nearer ones.
gollark: > I'd say exercise is pretty fun if it's combat sportsI should probably try that (those?) when stuff reopens here.
gollark: Exercise is already pretty not fun, but I don't think I'd prefer to be electrocuted at the same time.
gollark: I mean, probably? But you would still have to sit there being exercised. And there would probably be issues with them not being coordinated properly with the rest of the body.
