I can tell you the exact moment when I started thinking about longevity in a serious way. It happened on March 10, 2023, at 10:20 P.M., in a hospital delivery room ablaze with overhead lights. I stood bedside, my hand crumpling under my wife鈥檚 grip, as a tiny, screeching alien, an eggplant with eyes鈥攐ur daughter, Esme鈥攕lipped into the hands of the attending ob-gyn. At 56, I became a father for the first time.
Until Es arrived, the grand total of my thoughts about aging could be summed up in a line my father likes to say: 鈥淚t sucks getting old, but it beats the alternative!鈥 Now as I stared into her little purple face, I wanted every healthy minute I could get. I began to imagine all the things I鈥檇 be able to show her鈥攎ountains, rivers, books (made of paper), and how to mix the perfect margarita. By the time we got home, I was no longer the center of my universe. She was.
With this new cosmology in mind, I sat down with Peter Attia鈥檚 book, , cowritten with 国产吃瓜黑料 contributing editor Bill Gifford. The book has clearly resonated with a lot of people. It sold more than a million and a half copies in less than a year and has been a fixture on the New York Times bestseller list for nearly as long.

I approached it with trepidation. I鈥檝e been writing about health and fitness for more than two decades, and most things that promote 鈥渓ongevity鈥 give me hives. Why we die, and why we don鈥檛, involves enormously complicated science that鈥檚 difficult if not impossible to research conclusively. Dudes鈥攊t鈥檚 almost always dudes鈥攚ho claim they鈥檝e got it figured out are suspect by default.
Outlive, I soon learned, isn鈥檛 about death per se but about decline. Attia believes that you can prevent decline鈥攐r, as he puts it, 鈥渟quare the longevity curve鈥濃攖hrough an aggressive combination of exercise, lifestyle (nutrition, sleep, etc.), and elements from personalized health care, or what he calls Medicine 3.0. Can getting old suck less? He says that the answer is a resounding yes.
Attia, 51, is a licensed physician who runs a concierge telemedicine practice from his home and fitness HQ in Austin, Texas. To be a patient of his is rumored to run into the six figures annually. (He won鈥檛 disclose this number.) He鈥檚 also a rising star on the self-improvement influencer circuit, appearing frequently on podcasts hosted by Rich Roll, Andrew Huberman, Tim Ferriss, Joe Rogan, and Rhonda Patrick, among others.
In addition to his guest appearances, Attia produces his own podcast, The Drive, along with a weekly newsletter and a robust stream of social media content. He has a million followers on Instagram alone. You might even have caught him as the doctor on the Disney+ show Limitless with Chris Hemsworth, a.k.a. Marvel鈥檚 Thor. Want more? You can sign up for the expanded, members-only version of Attia鈥檚 output for $149 a year. Or splurge for his online longevity video course, Early鈥攅ssentially an enhanced, interactive version of the book鈥攆or $2,500.
I spent months immersed in Attia鈥檚 ideas, including his book, podcast, newsletter, and the Early program. Some of the advice in Outlive鈥攇et vigorous exercise, don鈥檛 eat too much or too little鈥攕eemed like it had been around since Jack LaLanne pulled on a stretchy unitard and started doing push-ups. But overall I hadn鈥檛 seen anything as comprehensive and visionary as Attia鈥檚 approach.
In Attia鈥檚 view, Medicine 3.0 is a paradigm shift from the pills-and-procedures protocol (Medicine 2.0) that is the current health care status quo. It鈥檚 heavy on prevention and arranged into five pillars: exercise, nutrition, sleep, emotional health, and what Attia calls 鈥渆xogenous molecules鈥 (pharmaceuticals, supplements, and so forth). They鈥檙e all important and get appropriate play in the book, but exercise reigns supreme as 鈥渢he most potent 鈥榙rug鈥 in our arsenal,鈥 he writes in Outlive. 鈥淭he data are unambiguous: exercise not only delays actual death but also prevents both cognitive and physical decline better than any other intervention.鈥
Exercise breaks down further into subcategories: strength, stability, aerobic efficiency, and peak aerobic capacity. The goal is to obtain optimum fitness in each of these, since they鈥檝e been shown to form a powerful shield against our biggest health threats: cardiovascular disease, cancer, metabolic dysfunction, and degenerative neurological disorders鈥攚hat Attia refers to as 鈥渢he four horsemen.鈥
Fitness sounded like good medicine to me, but the emphasis on exercise also prompted a lot of questions: What kind? How much? How hard? I reached out to Attia鈥檚 camp, asking if I could essentially become a patient for a few days and write about his methods. They said no to that鈥herr doktor is extremely busy鈥攂ut after months of back and forth they agreed to let me come out for a couple of days last April, to meet him and go through some fitness assessments. I felt like I was doing pretty well鈥擨 rode my mountain bike and lifted weights regularly, among other things. But what was I missing? What should I be doing going forward?
The timing was good, because Attia was preparing to open a new facility in Austin called 10Squared, a sort of hybrid testing lab and training center that will cater to his existing patients and a new cohort of select members. His team sent me an NDA ahead of my visit, with the caveat that this would be a black-box project until I鈥檓 informed otherwise. This struck me as over the top for what sounded like a fancy private gym, but sure, why not? If that鈥檚 what it took to finally get a taste of the secret sauce behind Outlive, show me where to sign.
