But when I got up, my lungs were empty.

I had been in the water for quite some time.

And

I knew what was going to happen.

So I decided to just be the plank, you know, not move and don't do anything, just open my mouth and try to suck oxygen.

But obviously oxygen at 6,000 meters, 20,000 feet, there is not that much.

It's about a little, it's 48% of what you breathe at sea level.

So although it was noon yesterday,

at that time, the sky stayed pretty dark and starry for about a minute or two.

Oh my God, yes.

Oh, you could.

I mean, the fact that I was already seeing dark was a real sign that my brain was starved of oxygen.

And I had one of my friends or colleagues on the shore just telling me because I'd been under for a little while and say, is everything okay?

And I remember trying to say something and I was just like, that's I think the best lie I ever, ever.

I gave the thumb down.

No, because I knew I was going to be okay, but it took me to be still for a few minutes.

You know, I think...

You probably can get good or better at freediving by training.

So you have different techniques.

You can train in swimming pool and you can say, you know, frankly, for me, I go at the bottom of the swimming pool and I sit there.
