What is the closest you've come to killing someone?
I'd reckon with most people it would be with a car, but has anyone ever punched someone and they've fallen over and been seriously injured from falling over.
I was in a fight once and the guy ran at my waist with his shoulder in my stomach and when he pushed my back banged his head on the wall. Was in a coma for 4 days. Made a full recovery thankfully.
