I’m not thinking of virus or illness. Just physical injuries. Every paper cut, burn, broken bone, stubbed toe, bonked head, etc.
You receive all those injuries right now, in a single moment.
I think I would lose an arm and maybe an eye, plus lots of brain damage and bleeding, but otherwise I think I would live.
It’s a good question, because when you think about it, surgery is a combination of carefully controlled intentional injury, and repair of that injury.
