I tweaked my knee whilst practicing high-gravity Jupitarian Jiu-Jitsu a few hundred years from now. Rolling in that atmosphere is way too stressful on my joints. I had to quit. My pal Julian encouraged me to give micro-gravity martial arts a try, so I hopped in the janky time machine and headed over to Jerry’s Dojo, which he recommended.
Jerry spent several years as a Space Force Seal perfecting his hand-to-hand aeronaut fighting skills. He never got a chance to use them in an actual combat situation because, well, even in this timeline, there’s no one to tussle with out there. Fermi paradox in full effect. Either way, JJJ looks like a blast and it’ll be fun to go floalling (they really coulda thought of a better name for it) with the guys.
