Thanks for sharing this FB.
Curiously on this topic, and I never heard of this guy, but his message (if you watch the video in the article, is important), that is, the power we have to heal ourselves.
One small example from what he seems to be saying about helping our immune system....in my POIS history, one of the features, particularly ten years + ago was, I used to suffer so many colds, 15-20 colds a year.
However, since I started taking cold showers after a hot shower some years back, I have not had one cold in over 3 years. It is helpful, because having a bad cold when in POIS is demoralising, like pouring flames on a fire when in POIS, it is like having a seriously bad flu, and it just runs you down even further.
I am not sure I will take up burying myself in ice like this guy, but it shows again the power of the mind, how we seem to have our own internal pharmacy (if we can access it) and the probably the even greater power of the brain !
