I first read about this sort of thing when I was a lad and grabbed every oddball science book I could. There's a famous case of a bloke who worked on the railroad in the USA back in the 1890's (I believe), he was tamping an explosive charge with the blunt end of a railroad spike when the charge went off and drove the sharp end through his head. When the surgeon removed the spike, he got off the operating table and put his shirt back on, and was getting ready to walk out of the room before the astonished surgery team could stop him. He lived, but had a complete change of personality and in some author's opinion suffered a lobotomy from the injury. What's totally amazing is that he lived through the experience at all ...
