That's a good point. Granted I have no idea how bad the conditions or circumstances were that this guy was in but taking off your own leg after only 11 hours seems a bit over-eager to me. I'm not sure if I could actually do it if I had to but I'm pretty sure I would lay there a lot longer than 11 hours before trying unless there was some unknown intervening issue that forced me to sooner. I wonder if this guy saw the movie "Saw" too many times.
