Yes, we were trained.

We were trained like astronauts for three months.

I spent more time.

I had a joke that if somebody wanted to reach me, they better put a phone line at the bottom of the swimming pool because this is where I was.

So we trained and we trained.

And our manual about the safety was about that thick.

So it was a real operation.

That was three years into it because when you're freediving in the years prior, there is no risk.

You don't have any other gas in your lung than what you're breathing.

The only risk is come short of air and then you're in trouble, which happened to me one time, seriously.

Well, all these lakes I had altitude, they are cold.

They are the minimum temperature that you can have on bodies of water, clear bodies of water, which is 4 degrees C. It's very, very cold.

It's like an ice bath.

Yeah.

So you cannot just dive with a wetsuit.

So the idea was to take a dry suit.

And I learned how to freedive with a dry suit, which is really the worst thing you can do.

So a dry suit, a wetsuit is usually what you use in the ocean when it's not too cold.

You can use also dry suit.

But the wetsuit basically is going to keep you warm because water is getting into the suit.
