Viceland is a TV channel, 271 on Direct don't know Dish or cable, that has some awesome programming IMHO. I saw a piece on Wim Hof:

that absolutely flabbergasted me. At first I thought he was crazy until I saw the effects of his program on the host of the show. Wow!
One of his beliefs per his website is:
Strengthen your body and be able to prevent disease
I tend to believe the body is a self healing organ but forget that I think that way when my medical problems rear their ugly heads. (Won't discuss my personal problems.)
If I can remember his breathing exercise regimen the next time I am at the gym I will begin my routine doing it. I'll let you know how it works.
Love to hear everyone's take on Wim and his program.
