If he manages to popularize something that is highly useful for people and costs nothing to do, how is he a joke? I'm sure 99% of the people are aware that Wim Hof didn't invent therapeutic breathing.

I have a big yoga chart on my wall. It shows that Yoga has been split and changed and derived from and iterated from for many many years. Seems like a bit of a joke to suggest that this specific iteration (if it even is that) is less valid simply due to a name that is geographically different.

I'm torn on this comment. The guy has done some amazing things with what he's learned and he has helped a lot of people. He also went many many years on this angle and only recently hit the big time. But yes, he didn't invent or discover these things, he repackaged them.

"Everything is a remix"

By this rationale, if I bring aspirin to some tribe that never had it, I’m a joke?

If you changed the name from aspirin to "david38's awesome headache cure" wouldn't that make you some kind of a joke?

Does the Indian science couple breathing with cold therapy?

I know what you are saying and I understand why you are getting downvoted. I dont know about Wim Hof but I hope he has preserved the whole spirit of yoga and not just cherry picked a few techniques. Yoga works on a much deeper level than just curing ADHD if done in the right ambience. Even a moderate yoga practitioner raises and expands their consciousness from oneself to being coextensive with everyone and everything.

Thats probably the reason why the author of this comment feels that it is far better going to the source rather than cherry picking a few practices.
