The mind does have extraordinary powers. I saw this so many times as a Paramedic I can't count them. I had people fight injuries that should have without a doubt killed them and they survived. It was almost eerie, most definitely unexplained. A good example is in BUDS classes. The abuse and demands on the bodies of SEAL candidates should kill anyone. Extremes and variance of temperatures, sleep deprivation, food deprivation and other extremes SHOULD shut the human body down cold. What gets them through, mental will to overcome! Scary what the body is capable of with the right mind set. 😮 Yes. I think the body can produce changes just based off of mind set. Too many examples to disprove this. 🙂
