I like to joke with my kids there is no need to whine and complain about pain unless you are bleeding or a bone is sticking out. I told my boss about this and he said, “Yeah if you get your arm cut off your reponse should be “Boy that’s going to make a mess””.
Via Fark: Hiker cuts his arm off and repells out of canyon. There is more than one story of people cutting off a limb and taking themseleves to the hospital.
Just goes to show the survival ability of a human.
