I was in an accident a while ago that renders me unable to bite my nails anymore. I’ll live and I’d rather have given up this habit voluntarily, but I might as well mark it ‘done’.

I’m only marking it ‘not worth it’, because the injury was severe, painful, nearly deadly, and I’m not going to be 100% ever again. A hospital stay, some surgery, and a long rehabilitation process makes this one not quite worth the effort. At least I don’t gnaw my nails off anymore, though.
