There was a thread where wca was in danger of losing a foot due to an accident (obviously, it’s wca) but in the end he opted for some other therapy. I shudder to think what would happen if he decided to build a guillotine though.
I seriously contemplated elective amputation of my little finger a few years back. I broke it badly playing cricket, across the joint so now it won’t bend more than about 45 degrees, and it sticks out like I’m drinking tea from a china cup. Initially I kept catching it on everything, and as it was serving no purpose I really thought I’d be better off without. But over time I’ve made allowances and now it doesn’t really bother me, except when I have a pocket of change. Because I can’t make a proper fist with that hand, if I get a handful of change in that hand it all falls out of the bottom!
