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.
I’ve never been severely injured enough for it to be seriously dangerous to my health as far as I’m aware but I would get the shit beaten out of me instantaneously and probably start bleeding from the mouth because I would definitely count getting my wisdom teeth ripped out.
