Based on the true story upon which the movie 127 Hours is based, about a man who amputated his own hand after it was trapped under an 800-pound boulder.
You are trapped in a slot canyon with your hand under a boulder that won't budge. You are out of food and water with little hope of rescue. Do you attempt to cut your own hand off, breaking the wrist bones if necessary, to get out?
I don't want to think about it
