I know a guy who did the same thing, but he only lost an arm. Only.
This is only part of his pattern of self-destructive behavior. He is in and out of jail for one thing or another, as well as being an alcoholic. He almost lost a leg to infection a while back. One time while drunk, he fell and broke his nose nearly off his face. Sometime after that, his friend who went our church, and our pastor, were driving him to a rehab clinic, when he reached out from the back seat and pulled the wheel all the way over, sending the car all the way across three lanes of freeway and almost off the road.
About two years ago, my church was putting together a building, and he did a lot of the steelwork for us, with his one arm. It was quite something to see him up in the rafters, later on, carrying a nail gun and smoking a cigarette, all while balancing on the boards. He said that the whole time he was working on the church he was dry, but after that he fell right off the wagon.
