What's your stance like when you're sanding up high? I messed up my rotator cuff by not keeping my elbow tucked in, could be similar.

Yeah that's key. Seriously, running out of battery mid-fade is the worst. It totally wrecks your rhythm. I was doing a really detailed beard line once and my main clipper just quit. Had to grab the backup, but it wasn't set to the same guard. Messed up the whole transition and I had to fix it. That's when I went and got a whole extra charging base too. Never letting that happen again.

Wonder if that scooter is already starting to build its own little ecosystem down there. Stuff like that, once the battery acid and oils leak out, just becomes a weird artificial reef. Tiny things start living on it, then bigger fish come to eat those things. It's a trash problem for sure, but sometimes the line between litter and habitat gets real blurry real fast underwater. Makes you think about how even our junk gets folded back into the system, for better or worse.
