I've been lucky---was working on back of a movie projector console, the 2.5x4 sheet steel back got away from me, dropped on my toe. They heard me in all six theatres, and over the phone in corp. headquarters. Don't know if I broke anything, but the blister was the size of a silver dollar, and was a unmitigated varking pain to drain by myself... The better half (Momofone) had me beat---she threw blood clots in her lungs, and was sent to the left coast to have them removed via open chest surgery---they had to "stop" her on the table, chill her down, and take a nice leasurly five minutes to debride all the blood vessels in her lungs, sew her up and cold-boot her. We had 40Kg of LOX in the bedroom for three months to assist her breathing. After that I resolved not to do anything stupid--I hate hospitals!
