This explains the rise in back pain in our society today where we subcionsculy think ourselves into having a condition due to the rise of media making us believe we do. RSI epidemic in Australia is the best example of this.
This reminds me of what happened to me. Despite my sore back, sneezing never bothered me. Until people around me saw me sneeze and said, “That must really hurt.” It did not initially. But after a few more of those comments it started to really hurt.
An idea got a hold of my brain and it soon became my new reality.
