Nowadays I've started doing the wim hof method and it's unbelievable my body can endure 7°c bath and I don't feel that cold or fall sick taking an ice cold baths everyday even during winters. The reason I'm mentioning this is because it really seems our minds are much more capable of things for which common sense goes against.
I think like the way germs were discovered which changed our understanding of medicine, within a few decades it will also become a norm to assess patient's mental condition before checking for physical and hopefully using the mind to cure a lot of disease. I feel like a hippie saying these things but after sarno and wim hof I've become more open to the power of human mind.
