I went to an EMT class over the summer between my first and second year. It was a great program, taught by a crusty old Paramedic with more horror stories than I had ever imagined. One day in particular I remember best.  He came to the front of the class and showed us accidents that he had seen.  Cars and bodies mangled and disfigured in ways I could never have imagined possible. Watching us cringe, he put down the remote to the slide show.
