But he's there every year.

We're going on four years now.

I'll see him in June.

We might come together there on altitude.

Yeah, great.

I've been a mountain guide for 10 years.

And I know I did some feats over there.

Running and breathing makes me able to go faster than normal and in high altitude.

And so I did it with 26 people with Crohn's disease, arthritis, cancer, asthma.

We did it all in record time, just using the breath.

Using the breath enables us to...

to go deeper into our physiology and to be just a little bit upfront the impact of nature itself, whatever that is.

And one of them is the cold.

The cold is a power which with the same awareness we were talking about, a little bit more breathing, just breathe a little bit more than you feel you need.

That is consciousness.

That consciousness I use.

I use, for example, in a scientific experiment with a perfusion vest, which is used by firefighters to stay cool.

They get icy water flowing through in their shoes.

I use that after knee surgery.

In their vest.
