You can...

tweak your ankle, you know.

And then you have other risks like altitude sickness, how you prepare for that, how you recognize that.

These are the yellow risks.

And then the red risks.

The red risks are what they call the acts of gods, the kind of thing that they can happen.

You know there is nothing you can do about it, and then you accept that when you do that.

So those are volcanic eruptions when you're in this kind of environment, earthquakes,

And everything that, and avalanches, for instance.

No, it's not shaking.

That's the interesting part of it.

There was a whole background of things that happened that day when we started off.

But we got to 50 meters from the summit.

And I have part of my logistics team that is at the foot of the mountain.

And being so close to the summit, we have to go under an overhang of lava.

So it's just like we are just under this big vault of lava.

And it's actually beautiful.

If you want something beautiful, it's the Altiplano seen from 20,000 feet.

It's just absolutely stunning.

The colors are that of early Earth, which means primordial Earth.
