Has anyone seen this talk?
I would say that Bernd Friedlander just rePeats most what Ray Peat says.
But I want to ask you something regarding CO2 that I couldn't comprehend. On the minute 37:40, he teaches a breathing technique that I've never heard to increase CO2 in the body.
As I see it, it seems that we are actually increasing O2 levels. I mean, inhaling O2 and then blowing out all the CO2, how does it increase our CO2? Could anyone explain how this actually works in our body?
I must say that I like the technique though.
