I've never broken a bone, though I had a close call with my right arm. I was in gym class and we were doing basketball exercises, I managed to get a good jump but then I lost my balance mid air and I landed right on my back but my arm hit first and the pain just shot up my arm. Turned out to be a bad sprain, but I couldn't use for it a month and I had to write an exam with my left hand...the writing was so bad I got like a C- lol
