It’s pretty specific but I’m on some Quasimodo, 1950’s Chinese prisoner of war type beat when it comes to fitting into small spaces and generally just monkeying about
It’s really useful as a sparky, makes running cables under floorboards a lot easier when I can monke crawl under them with pretty much no issue, and it saves using cable rods even when we get a really tight one where most people wouldn’t be able to fit
Best one I had was trying to get under a floorboard with like a 1ft x 1ft gap that I managed to squeeze myself through. Getting out was a lot harder
Also helps with working in lofts
And uhhh I can say the alphabet backwards I guess
