Keep a lot of super glue, and black electrical tape on hand. When you cut yourself you can glue yourself together again. We had a fellow in the state shop where I worked and he did our tractor work. One day he really cut himself bad and the boss asked if he want to go to the Dr. He said, "naw just give me some of that super glue. I thinks to meself, he is going to get gangrene or no telling what from this. Next day, I asked him how is the cut today? He says, "a little sore."
If, it had been anyone else he would have had a severe infection. But, he didn't.
SO, just keep the super glue non surgical kind and electrical tape on hand, which he used. I guess ones immune system gets used to it after a while.

Of course I am just being facetious, SO, don't take this to heart. I realize there is a medical grade of the stuff so I will leave that up to N80.
