My guest today, Peter Atia, makes a return visit to the podcast.

He's a physician who specializes in the topic of living a long healthy life.

It's taken him seven years to collect and organize his insights into his first book.

It's called Outlive, the Science and Art of Longevity.

Longevity is only half about length of life.

We have to be just as concerned with quality of life.

Welcome to People I Mostly Admire with Steve Levitt.

This is not your run of the Millself Health book.

Peter is one of the smartest people I know.

And this book represents the absolute cutting edge of scientific knowledge.

The collective wisdom of Peter's decades-long obsession

with the question of living longer and better.

Peter essentially explains how the human body works

and what that implies for the steps you can take to slow down the aging process.

In the time since I got my hands on the manuscript,

I've changed many aspects of my daily routine,

the way I exercise, how much I sleep,

I've even gotten serious about flossing my teeth.

Hey, Peter, it's so great to have you back on the show.

Thank you so much, Steve, for having me back.

You know, with most of my guests, even the best ones,

I feel like a single episode is the exact right amount of time.
