Pain, pain tolerance —

First, the obvious thought is pain is good. If your body never admitted any sort of pain signals, you would probably die. To experience large doses of pain is certainly terrible, yet when you compare it with the pain of death, even the highest doses of pain is preferable to death. And the good thing with pain is that it never lasts forever… Even the highest dose of pain, sooner or later the pain will subside, or at least lower the degree of pain.
