I heard about a guy who had written books on two topics.

One was about breathing and the other was about free diving.

I can honestly say I've never been very interested in breath work. And free diving?

Will you dive deep underwater holding your breath? I can't think of anything or terrifying and unappealing.

So the fact that I'm excited to interview James Nester,

a journalist who I only know from his books on free diving and breathing

should tell you something about how interesting this man is.

I did not set out on this journey to prove or disprove anything.

I talked to the freaks, but I also talked to renowned researchers at top institutions.

I talked to everybody. They said, this is so easy if we know it works. why aren't people doing it?

So what I want to do is give people information

so that they can choose what road they want to take.

Welcome to take. Welcome to people I mostly admire with Steve Levitt.

James Nester's books have forced me to rethink everything I thought I knew about the human body and its limits.

And its work is not just applicable to elite athletes or people trying to dive 300 feet underwater,

I've changed how I breathe when I sleep at night

because of research in this book.

Listening to James Nester, I suspect

you too will learn something that's applicable to your life.

People sometimes say to me,

I love Freconomics.

What other popular economics book would you recommend?
