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.

Popular interest in living longer is hardly new, but it spiked in the past few years. Reasons for this aren鈥檛 exactly clear. The pandemic reminding us of our mortality? A growing number of Boomers looking to redline their retirements?

Our fixation on longevity is rising at the same time that our health appears to be sinking. A 2018 study from researchers at the University of North Carolina made waves by concluding that only 12 percent of Americans are metabolically healthy. What鈥檚 more, according to data from the CDC鈥檚 National Center for Health Statistics, average life expectancy fell between 2019 and 2021, the biggest decline since the early 20th century. Granted, that statistic was affected by COVID-19, but chronic disease played a significant role as well.

The renewed obsession with healthier living has given rise to some longevity-oriented products and services, many with a fitness slant. No doubt the success of Outlive helped prime the market. Equinox, the upscale fitness chain, recently launched a $40,000-a-year wellness and longevity package called Optimize, which includes blood analysis, a personal trainer, and individualized sleep coaching.

In New York City, a startup called Continuum goes one better: for $10,000 per month, you get a precision health plan crafted by AI, a full biometric analysis, massages, nutrient-rich IV drips, and other luxe benefits, laid out in a swanky 25,000-square-foot private gym in Greenwich Village.

I had a hard time reconciling the new longevity bling鈥攁nd the hefty price tags鈥攚ith the lives of actual people living to be 90 or 100. I doubted that most of them had ever heard of VO2聽max or set foot in a weight room. Maybe they were all just genetic-lottery winners?

I reached out to Dan Buettner, the author of Blue Zones, the bestselling book turned Netflix series that takes a close look at five places in the world where people live the longest. Buettner is a journalist, not a doctor or scientist, but he鈥檇 spent ample time with centenarians. He said that he liked Outlive and thought the science was sound, but he was skeptical because following its advice already 鈥渞equires a person who is two or three standard deviations from the norm when it comes to discipline, income, and presence of mind.鈥

Attia arrived in the longevity field via a circuitous path. He grew up in Toronto, the son of Egyptian parents who immigrated to Canada. In Outlive he reveals that, as a child, he was physically and sexually abused鈥攈e doesn鈥檛 say by who, just that it wasn鈥檛 a family member. As a teenager he took up boxing, which helped him cope with the trauma. 鈥淚 got to punch bags, and people, and that channeled my anger,鈥 he writes. Despite this and other outlets, emotional problems followed him into adulthood.

His past helped set him on a course toward medicine. As an undergraduate at Queen鈥檚 University at Kingston, in Ontario, he volunteered at a shelter for abused kids. He attended medical school at Stanford University, and then did a prestigious surgical residency at Johns Hopkins before dropping out in his fifth year. Something wasn鈥檛 quite working for him in that world. To Attia, traditional medicine seemed entrenched, resistant to new approaches and new ways of thinking. He believed that there had to be a better way.

Attia believes that you can prevent decline through an aggressive combination of exercise, lifestyle, 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.

After bailing from medicine altogether, he took a job with McKinsey and Company, the global management-consulting giant based in New York City. He had a strong penchant for mathematics, which played well at McKinsey, where Attia developed a system of thinking involving frameworks, risk, and probability that would eventually become the foundation of his approach to Medicine 3.0.

Attia was also a serious amateur athlete who pushed his own fitness to the edge. In boxing he competed at an elite junior level. As an adult, he transitioned into endurance sports, throwing himself into cycling and swimming. Among other impressive feats, in 2005 he swam from Catalina Island to Los Angeles鈥攁bout 20 miles in 10 hours and 34 minutes. More recently, he鈥檚 focused on rucking, which involves strenuous hiking with a weighted backpack鈥攊n his case, often 50 pounds or more.

He also started moving back toward medicine, this time in private practice. Around 2014, he wrote down his manifesto about health, ideas that would eventually grow into Outlive. The key to a longer life, he realized, was keeping chronic disease at bay. Nothing accomplishes this better than exercise, Attia argues.

This wasn鈥檛 merely an overzealous proclamation from a man obsessed with his own fitness. Scientific literature showed clearly how effective exercise could be in preventing, and even treating, chronic disease. Such thinking started to become popular in the modern era thanks in part to books such as W.鈥塃. Harris鈥檚 Jogging (1966) and Kenneth Cooper鈥檚 Aerobics (1968), which helped connect the dots between fitness and health, and is sometimes credited with helping launch the running boom of the 1970s.

The data was so convincing that, in 2007, the American College of Sports Medicine joined forces with the American Medical Association to launch Exercise Is Medicine, a trademarked initiative to help facilitate the adoption of fitness metrics among medical professionals. Doctors, they urged, shouldn鈥檛 just check your blood pressure. They should track how much physical activity you get every day.

鈥淭here is no chronic disease that exercise doesn鈥檛 touch,鈥 says Robert Sallis, a clinical professor of family medicine in Fontana, California, and founder of Exercise Is Medicine. 鈥淚t makes so much sense that this ought to be a first-line prescription.鈥

Though they鈥檙e great in theory, attempts to rely on fitness as either prevention or therapy haven鈥檛 worked well in practice, Sallis says. Busy physicians rarely have time to talk to patients about their diet and physical activity, and if they do the conversation is often brief and vague. 鈥淚t鈥檚 frustrating,鈥 says Sallis. 鈥淚t鈥檚 all about pills and procedures. We鈥檙e not putting ads on TV saying, 鈥楢sk your doctor about exercise.鈥欌夆

My conversation with Sallis reminds me that so much about exercise doesn鈥檛 mix well with contemporary culture. We鈥檝e engineered most movement out of our lives; we eat too much, drink too much, stress too much, and sleep too little. For many exercise is arduous and unpleasant, and it has to be stacked on top of other demands, like working a job (or jobs), raising a family, and managing the relentless addictions and distractions of late capitalism.

If that doesn鈥檛 make things hard enough, we also aren鈥檛 particularly well adapted to exercise, argues evolutionary biologist Daniel Lieberman, author of Exercised: The Science of Physical Activity, Rest, and Health. Viewed through a Darwinian lens, being lazy鈥攖hat is, conserving energy鈥攊s a survival tactic. According to Lieberman, exercise is a 鈥渨eird鈥 modern contrivance invented to replace eons of physical effort.

As has been true for most of human evolution, exercise鈥攑hysical activity鈥攎ust be 鈥渘ecessary鈥 and 鈥渇un鈥 to be sustainable, Lieberman writes. Absent those qualities, we鈥檙e swimming against an increasingly swift current, if not already being washed downstream.

I arrive in Austin on a cloudless 70-degree day, the kind that provides ample motivation to get after it. Hordes of people are out walking, running, cycling, and paddling around Lady Bird Lake, on the edge of town.

I鈥檓 scheduled to meet Attia at a posh golf resort a few miles west of the city. One of his assistants arrives in advance to help me find a suitable spot for the interview; we settle on a quiet bar near the lobby called Jim Bob鈥檚. Attia arrives late, explaining that he was dealing with a patient emergency. He doesn鈥檛 seem very psyched to be here. When I ask if we still have the scheduled two hours, he says: 鈥淚s this going to take that long?鈥

In person, Attia is buff and a little imposing. People I鈥檇 talked to about him before coming to Austin used words like 鈥渋ntense鈥 and 鈥渟erious,鈥 and I can see why.

We make zero small talk as we take our seat at a quiet table near the bar, which has a wall full of fancy booze behind it. 鈥淚t never hurts to be close to the tequila!鈥 I joke, trying to lighten the mood. Attia doesn鈥檛 laugh. As we start our conversation, he takes out his phone, sets it on the table, and says that he鈥檚 going to record the interview as well.

When it comes to merging medicine and fitness, part of the problem, as Attia sees it, is that most physicians don鈥檛 know how to manage it鈥攐r if they do, they aim too low. There are lots of unanswered questions about exercise as we get older. How much, and what kind, is optimal versus merely sufficient?

When I bring up that the federal physical-activity guidelines recommend a relatively modest 150 minutes a week, Attia interjects: 鈥淚 would never say that.鈥

鈥淚 know you wouldn鈥檛. But that鈥檚 the baseline for a lot of doctors.鈥

鈥淲ell, that鈥檚 sort of the first failure,鈥 Attia says. 鈥淚nstead of telling people what to do, we should be telling them what we鈥檙e going to be measuring them against. So it鈥檚 more important to say, We want you to have a VO2聽max that is above this range. We want you to have muscle mass that is above this range. We want you to have these strength metrics above this range. And then the question becomes: How much are you willing to put into this?鈥

Attia doesn鈥檛 just want you to exercise. He wants you to train. I mention that I know a lot of fit, active people in their fifties, sixties, and beyond who spend ample time running, hiking, or cycling, but not much else.

鈥淚 think you always want to differentiate between recreation, play, and training,鈥 he says. 鈥淚 think recreation and play are really important. They鈥檙e the why. But to do those things you have to train.

鈥淟ook at the greatest tennis player who ever lived, Novak Djokovic,鈥 he continues. 鈥淭o be the world鈥檚 best tennis player, you have to be very strong. You have to be very supple. You have to have great balance. You have to have an amazing aerobic base of fitness. You have to have incredible anaerobic power. And just playing tennis isn鈥檛 enough to do that. And so it goes for everything that a person might want to do, whether it鈥檚 skiing or playing pickleball or, in my case, driving a race car or doing archery.鈥

Attia isn鈥檛 suggesting that we all strive to become the world鈥檚 best tennis player, but he does want us to be the best old people we can be. In Outlive he talks about what he calls the Centenarian Decathlon. This is a list of things you鈥檇 like to be able to do on your 100th birthday, or whichever final decade you reach. The idea behind the decathlon is to develop broad, well-rounded fitness, as opposed to defaulting to things you鈥檙e already good at, or simply enjoy.

鈥淲e鈥檙e not talking about creating immortal souls who, in their eighties, look like 20-year-olds,鈥 Attia says. 鈥淭hat鈥檚 science fiction. But you can be 80 and still have the body of a 60-year-old. How do we make that the norm as opposed to the exception?鈥

While you can start or expand your program at any age, it鈥檚 preferable to cultivate a high level of fitness early in your life, when your body is more adaptable. As you age, you can adjust your training to sustain it, but train you must. You can follow your progress鈥攐r perhaps lack of deterioration is a better way to look at it鈥攗sing a suite of fitness metrics, the same way you track blood biomarkers as an indication of your general health.

I ask him what he thinks of the criticisms I鈥檝e seen aimed his way, like the idea that he may be peddling a fantasy about longer, healthier life spans, given how complex the subject truly is. 鈥淚鈥檓 not really familiar with these criticisms,鈥 he says. 鈥淏ut if you鈥檙e asking why should we do what we do to stave off a declining health span, I guess my question would be, What鈥檚 the alternative? Just accept it? So if someone asks me, Why do you exercise? I would say, What would you propose instead? To not?鈥

Attia answers my questions dutifully, even thoroughly, but the vibes are off. His foot jitters. His teeth are very white. I get flustered and lose my train of thought a couple of times. I鈥檇 arrived hoping for a couple of hours of Medicine 3.0 stoke, but I leave feeling like I鈥檝e been to a Medicine 2.0 doctor鈥檚 appointment鈥攊mpersonal and perfunctory.

The experience gets me contemplating the degree to which we have to quarterback our own health. As Attia writes in Outlive, Medicine 3.0 鈥渄emands much more from you, the patient. You must be well informed, medically literate to a reasonable degree, clear eyed about your goals, and cognizant of the true nature of risk. You must be willing to change ingrained habits, accept new challenges鈥 You confront problems, even uncomfortable or scary ones, rather than ignoring them until it鈥檚 too late.鈥

Gulp.

That evening I take a long walk around downtown Austin. A full moon is creeping up between tower cranes, and it casts a shimmering reflection across Lady Bird Lake. A crowd has gathered along the guardrail of the Congress Avenue Bridge to watch a famous attraction: the nightly swarm of more than a million Mexican free-tailed bats, the largest urban colony in North America, which live in the trusses. I wedge into a view spot until the bats emerge in a great pulse, rushing around the bridge and shoreline trees in a dusky murmuration. I think of bringing Esme here when she鈥檚 older to see the bat show鈥攖his and so many other natural wonders still ahead of her.

The next morning, I drive to 10Squared for my VO2 max test and a couple of strength assessments. I鈥檓 also scheduled for a DEXA scan, which will reveal my muscle-to-fat ratio, but that鈥檚 happening off-site, at a facility called the Fitness Institute of Texas, part of the kinesiology department at the University of Texas.

10Squared is a private facility for a very exclusive clientele, located in a small office complex in an Austin suburb. It鈥檚 not exactly Equinox, but I thought it was an interesting template for the way doctors might integrate fitness for their patients. One side of the modest space contains a squat rack, a chin-up bar, some free weights and kettlebells, and assorted other resistance-training equipment. The other side contains a stationary bike, a treadmill, a rowing machine, and diagnostic machinery. The place is strictly business, and it鈥檚 where Attia鈥檚 clients, many of whom live elsewhere, can fly in, go through a few days of testing, evaluation, and coaching, and then head home to dial in their personalized programs. Not surprisingly, nobody would tell me what it costs, or how one goes about becoming a client there, other than to say that there鈥檚 a 鈥渟creening process.鈥

I鈥檓 greeted by Luke Bennett, 10Squared鈥檚 amiable CEO. A former physician for Formula 1 race teams and an MD from Australia, Bennett is in his fifties but looks younger. He sets me up on a stationary bike and pulls a tight-fitting respiration mask down over my head to capture and measure my breath as I hammer away. I鈥檝e done this before, but it鈥檚 been a while鈥攍ike 15 years鈥攁nd I鈥檝e forgotten how claustrophobic it feels.

VO2聽max measures the amount of oxygen your muscles can utilize at peak effort. It鈥檚 the benchmark of cardiovascular fitness because it鈥檚 a picture of how well oxygen moves through your system. You can鈥檛 game the results. It has also, somewhat recently, become a useful predictor of longevity. If some fitness is good, is more better? Apparently so. Numerous studies have found that higher VO2 max scores correlate with longer life.

The test lasts about 12 minutes, starting easy and increasing in difficulty by increments until you tap out from exhaustion. You aren鈥檛 supposed to talk鈥斺渦nless there鈥檚 an emergency,鈥 Bennett says鈥攂ut you can indicate your exertion level by pointing at a reference sheet. By the time I鈥檓 pointing at the highest level (Very, Very Hard), I鈥檓 huffing and sweating like a racehorse.

My score tops out at 41.6, which strikes me as low, but Bennett says it鈥檚 actually pretty good for a guy my age. I鈥檓 quietly thrilled to see my report sheet include the word 鈥渆xcellent.鈥 Still, I鈥檓 a bit short of the Elite category, which requires hitting 50 or above. In Outlive, Attia states that he wants his clients to aim for a VO2聽max score in the Elite zone for their gender but two decades younger. In my case, that would mean a score of around 53, a daunting target based on what it took to hit 41.

That seemed highly improbable, but Bennett assures me I can get there, or close. And what, I ask, might it require? Something in the range of four to six hours of Zone 2 work, plus at least one Zone 5 interval session, per week, he says.

Zone 2 is the quasi-magical aerobic threshold, where it鈥檚 possible to burn fat as fuel more than you鈥檙e burning carbohydrates. Zone 2 is the kind of effort you can sustain for a long time. Zone 2 is pretty easy. I love Zone 2.

Zone 5 training is quite hard, but it鈥檚 mercifully brief. A popular Zone 5 workout involves four minutes of maximum effort followed by four minutes of recovery, done a total of four times. One of my big takeaways from testing is realizing how these zones actually feel. What I thought was Zone 2 was probably more like Zone 3 or even 4. My easy workouts have not been easy enough, I discover, and my hard sessions are not hard enough. I鈥檝e been trapped in the middle, a metabolic no-man鈥檚 land.

Once I鈥檝e recovered, I move on to a few strength tests. These are simple exercises, including a dead hang and carrying a loaded hex bar. Strength is another vital component of the longevity strategy, in large part because strength and muscle mass inevitably deteriorate as we age. I鈥檇 long thought of lifting weights as essential for athletic performance, regardless of your sport, but I hadn鈥檛 considered the impact on healthy aging. Not only does preserving lean muscle deliver metabolic benefits, but it also helps keep us mobile and stable. Falls are the leading cause of death after age 65鈥攖he fifth horseman.

Not surprisingly, given my cyclist鈥檚 approach to upper-body development, I fare less well at strength. The goal for the arm hang is two minutes. That doesn鈥檛 sound like much, but it鈥檚 surprisingly difficult. I don鈥檛 even make it to one minute.

The goal for the hex-bar carry is similarly challenging: carry your body weight鈥攊n my case 186 pounds鈥攆or 60 seconds. Once again I come up short. Not to worry, Bennett tells me. With a dedicated lifting regimen, I can meet these standards as well.

As I鈥檓 finishing the strength exercise, Attia arrives for a photo session. 鈥淗e鈥檚 here!鈥 one of his assistants calls out. I鈥檓 curious what he thinks of my results, but he doesn鈥檛 seem very interested and merely nods when Bennett says, lightheartedly, that I did pretty well for an old guy.

In the afternoon, I drive over to the Fitness Institute of Texas for my DEXA scan. 10Squared sends clients there since the machine, which costs more than $100,000 new, isn鈥檛 part of Attia鈥檚 inventory. DEXA has become a popular way to analyze body composition, because the imaging technology is considered the gold standard for this kind of measurement.

Rachel Watson, the Fit Institute鈥檚 upbeat director, is in charge of my body composition analysis. After Outlive was published, the institute saw its requests for scans nearly double, she tells me. The Fit Institute is happy to oblige (for a modest $75). It works with UT to provide research data, so collecting it from the public is a convenient source of information. The institute also offers VO2聽max testing, group workouts, and nutrition coaching.

As we chat about fitness trends, Watson writes something down on a pad. 鈥淲hat鈥檚 the buzzword everyone鈥檚 talking about these days?鈥 she asks.

I鈥檓 stumped, so after a moment, she flips the pad around to show me: longevity.

鈥淚t鈥檚 what everyone is fixated on now,鈥 she says.

鈥淎h,鈥 I reply, feeling dumb. 鈥淥f course.鈥

I lie on the table and try to remain still while the scanning bar moves slowly over me from head to toe. A few minutes later, Watson and I sit down at her desk to review my results. The data is enlightening, and better than I expect. At 186 pounds, with an overall body-fat composition of 15.4 percent, I fall right between Very Lean and Athletic. Watson is particularly happy with my visceral fat score, which tabulates fat accumulation around the midsection and organs. The average for men my age is 2.62 pounds. I come in at 1.21. She draws a smiley face next to the number.

鈥淣ow for the bad news,鈥 she says.

鈥淯丑-辞丑.鈥

鈥淵ou鈥檙e pear-shaped.鈥

Watson shows me how the numbers align with my body parts. Most of my mass is located around my butt and thighs: a cyclist鈥檚 build. I could use some work on my upper body, arms, and shoulders if I want to attain the coveted V look.

鈥淒on鈥檛 feel too bad,鈥 she says cheerily. 鈥淢ost men your age are apple-shaped. Their body mass is collected around their midsection.鈥

My disappointment must have lingered, because Watson reassures me that I am actually doing great. And did I know the Fit Institute also offers online strength-training classes?

I return home from Austin feeling fit but also realizing that fitness is just one piece of a complex puzzle. It left me pondering: Am I healthy? The truth is I鈥檓 not sure. I haven鈥檛 had a proper checkup in a few years. Chronic disease is insidious because it often begins鈥攁nd may creep along for years鈥攚ithout any obvious signs.

With renewed motivation, I text my doctor, a very nice but very Medicine 2.0 kind of guy, about scheduling an appointment. I want to put together a 鈥淏ig Workup,鈥 I write. He replies that he鈥檒l give me a call, but I don鈥檛 hear from him.

When it comes to sizing up your long-term health risks, family medical history matters a lot. Mine reveals a stark reality. My mother, a registered nurse, died in 2013 from breast cancer, at 75. My father, in his eighties, is still alive but lives alone and struggles to walk, fallout from a knee replacement gone bad and compounding cardiac problems. My sister, who鈥檚 a year younger than me and is my only sibling, fought weight issues for years until she recently began using Mounjaro, one of the vaunted GLP-1鈥檚, like Ozempic, used to treat Type 2 diabetes and, increasingly, obesity. In the course of a year, she lost more than 100 pounds鈥攖he most astonishing physical transformation I鈥檝e seen in real life. It鈥檚 clear that I don鈥檛 come from genetically impervious stock. The horsemen are right there over my shoulder, breathing down my neck.

Dan Buettner, the author of Blue Zones, said he liked Outlive and thought the science was sound, but he was skeptical because it 鈥渞equires a person who is two or three standard deviations from the norm when it comes to discipline, income, and presence of mind.鈥

In Austin, Attia told me that one of the biggest aha moments of his professional life was realizing that centenarians last as long as they do because favorable genetic profiles tend to keep chronic disease at bay. They die of the same causes as everyone else, but it just happens later. Attia didn鈥檛 buy that it鈥檚 because they live in blue zones or eat a special diet. 鈥淧eople love to rattle off the esoteric behavior of centenarians,鈥 he said.

The trick to emulating the long-lived, then, is to keep putting money into our fitness 401(k)s, so to speak. Jack LaLanne died in 2011, at the age of 96, from pneumonia, but reportedly he kept working out until a few days before his death. Could we all be like Jack?

鈥淭here are lots of people in the last decade of their life who are wonderfully happy with their children and their grandchildren, all those things,鈥 Attia said. 鈥淏ut I just don鈥檛 meet many people whose bodies aren鈥檛 aching and who aren鈥檛 thinking, God, I wish I could do something about this. And the truth of it is, most of those people didn鈥檛 do all they could to reduce the probability of that. We鈥檙e not talking about creating immortal souls who, in their eighties, look like 20-year-olds. That鈥檚 science fiction. But you can be 80 and still have the body of a 60-year-old. How do we make that the norm as opposed to the exception?鈥

Great question. I had some ideas, and exactly none of them involved six-figure training programs or the elite VO2聽max of a 37-year-old. As much as I enjoyed reading Outlive, and as strongly as I believed health care was ripe for a Medicine 3.0 revolution, I also knew that sometimes disrupting a status quo could backfire.

Case in point: On May 30, shortly before this story went to press, Attia posted a group photo on Instagram that included his 鈥渄ear friend鈥 Kevin Spacey鈥攖he embattled Oscar-winning actor accused of sexual misconduct. Spacey had been acquitted in several court trials, but Attia鈥檚 supportive post prompted widespread anger and questions about Attia鈥檚 judgment, including more than 3,000 mostly negative comments on Instagram.

Generally speaking, I didn鈥檛 want to confuse the message with the messenger; there is plenty to admire in Attia鈥檚 voluminous content. As one person on Reddit succinctly put it: 鈥淯se wellness and longevity influencers as a conduit to discovering interesting research(ers) and for general entertainment purposes. Otherwise apply a healthy dose of critical analysis like you should with anything.鈥

In my case I realized, happily, that I had already cobbled together my own low-budget Medicine 3.0 lifestyle. I live in Santa Fe, a small city nestled against the west flank of the southern Rockies, and cultivate a fitness-first lifestyle. I have easy access to trails for hiking and biking, which I try to do often; it鈥檚 Zone 2 pretty much every time I step out the door. For Zone 5, I just need to find a steep hill. My wife and I love to cook, and we default to a whole-foods diet without thinking much about nutrition. We enjoy an occasional drink or two. We socialize in person often. Good sleep is a priority, not an afterthought.

Twice a week, I drive an hour to work out at a facility called Elevate PHW (Performance Health Wellness), alongside clients who range from pro athletes to seniors with walkers. My friends are incredulous that I commute to a gym. I try to explain that, in addition to a great space and community, Elevate provides motivation and quality programming, which are both essential. I don鈥檛 particularly like lifting weights, and there are many days when I have to drag myself in. But I always go and am always glad; Elevate makes something I never enjoyed both necessary and fun.

I know my situation is unique, but the point is that many roads can lead to the same place. Ideally, the fight against age-related entropy is built into our routine and doesn鈥檛 demand a lot of mental energy figuring out what to do. What makes it work is consistency and sustainability.

鈥淭here is no short-term fix,鈥 Blue Zones鈥s Dan Buettner told me. 鈥淚f you want to live longer, you have to think about things you are going to do on a daily basis for decades.鈥

Our species has made some great progress, but we鈥檝e landed in a place and time that undermines our health: sedentary, anxious, increasingly toxic. More insidiously, health鈥攁nd by extension fitness and longevity鈥攖ends to break along socioeconomic fault lines, a disparity that grows every year. With enough resources, the wealthiest can buy a better body. But what about everyone else?

We tend to underestimate what it takes to implement meaningful change, which is often as dependent on our environment as it is on our behavior. Medicine 3.0 feels like an individual solution, but in reality it鈥檚 a subversive and radical systemic proposition that seeks to disrupt long-established institutions and hierarchies. It makes me wonder what kind of world my daughter is going to inherit. I hope I鈥檓 around long enough to find out.
