    A few, 7yo appendicitis which ruptured in surgery. 15yo Fell from 3 story high scaffolding and landed on my back. 11yo an adult repeatedly slammed my head onto a wooden floor: maybe not a near death but I had thought that that was the end. 18yo big hill at night friends figgered we would ghost it, brakes off keys out of the ignition, find break don’t work and scrabbling to put keys in ignition… I was drunk so I don’t remember much else but we all survived car had a dent on the bumper.
