You start hallucinating.

I don't know if you were hallucinating, but that's very common.

And all of these safeguards that you have built up, especially around your nervous system and emotion,

tend to release in certain ways.

So we know it absolutely affects your physiology.

I had the one bit of research, actually, there were many in the book that did not make it in is I went to a lab at University of California, San Francisco,

and breathed for an hour, just crazy hyperventilation as they had a catheter out and were recording my blood pH.

And they had to stop it because according to their measurements, my blood was so alkaline, which means I was blowing off so much CO2 that I should have been in an emergency room.

This guy is just like, this is the weirdest thing.

You should not be doing this.

This is unhealthy.

And yet I felt great.

Because our bodies are meant to be flexible.

So we know something physiological is happening.

On the other end, people claim that they're able to revert to their caveman selves or revert to different animals.

I think that some of that is where it gets a little showy.

I was in one like two hour long session where you're just hyperventilating for two hours and

Yeah, prove it if you're an animal.

No, this guy was doing it.

I shouldn't laugh.
