just the way it goes,” she said. But the person she truly was had been dead many years at that point.

      At first, because it’s calming, most children prefer to think that there are certain groups of people who are protected from death: parents, teachers, and themselves. Between 5 and 7, however, all children come to understand the universality of death. Every family member will die. Every pet. Every plant. Everything they love. Themselves, too. I can remember first learning this. I can also very well remember our oldest child, Alex, learning it.

      “Dad, you won’t always be around?”

      “Sadly, no,” I said.

      Alex cried on and off for a few days, then stopped, and never asked me about it again. And I’ve never again mentioned it, either.

      It doesn’t take long for the tragic thought to be buried deep in the recesses of our subconscious. When asked if they worry about death, children tend to say that they don’t think about it. If asked what they do think about it, they say it is not a concern because it will occur only in the remote future, when they get old.

      That’s a view most of us maintain until well into our fifties. Death is simply too sad and paralyzing to dwell on each day. Often, we realize it too late. When it comes knocking, and we are not prepared, it can be devastating.

      For Robin Marantz Henig, a columnist at the New York Times, the “bitter truth” about mortality came late in life, after she became a grandparent. “Beneath all the wonderful moments you may be lucky enough to share in and enjoy,” she wrote, “your grandchild’s life will be a long string of birthdays you will not live to see.”³

      It takes courage to consciously think about your loved ones’ mortality before it actually happens. It takes even more courage to deeply ponder your own.

      It was the comedian and actor Robin Williams who first demanded this courage from me through his portrayal of John Keating, the teacher and hero in the film Dead Poets Society, who challenges his teenage students to stare into the faces of the long-dead boys in a fading photo.⁴

      “They are not that different from you, are they?” Keating says. “Invincible, just like you feel. … Their eyes are full of hope … But you see, gentlemen, these boys are now fertilizing daffodils.”

      Keating encourages the boys to lean in closer to listen for a message from the grave. Standing behind them, in a quiet, ghostly voice, he whispers, “Carpe. Carpe diem. Seize the day, boys. Make your lives extraordinary.”

      That scene had an enormous impact on me. It is likely that I would not have had the motivation to become a Harvard professor if it hadn’t been for that movie. At the age of 20, I had finally heard someone else say what my grandmother had taught me at an early age: Do your part to make humanity be the best it can be. Don’t waste a moment. Embrace your youth; hold on to it for as long as you can. Fight for it. Fight for it. Never stop fighting for it.

      But instead of fighting for youth, we fight for life. Or, more specifically, we fight against death.

      As a species, we are living much longer than ever. But not much better. Not at all. Over the past century we have gained additional years, but not additional life—not life worth living anyway.⁵

      And so most of us, when we think about living to 100, still think “God forbid,” because we’ve seen what those final decades look like, and for most people, most of the time, they don’t look appealing at all. Ventilators and drug cocktails. Broken hips and diapers. Chemotherapy and radiation. Surgery after surgery after surgery. And hospital bills; my God, the hospital bills.

      We’re dying slowly and painfully. People in rich countries often spend a decade or more suffering through illness after illness at the ends of their lives. We think this is normal. As lifespans continue to increase in poorer nations, this will become the fate of billions of additional people. Our successes in extending life, the surgeon and doctor Atul Gawande has noted, have had the effect of “making mortality a medical experience.”⁶

      But what if it didn’t have to be that way? What if we could be younger longer? Not years longer but decades longer. What if those final years didn’t look so terribly different from the years that came before them? And what if, by saving ourselves, we could also save the world?

      Maybe we can never be six again—but how about twenty-six or thirty-six?

      What if we could play as children do, deeper into our lives, without worrying about moving on to the things adults have to do so soon? What if all of the things we need to compress into our teenage years didn’t need to be so compressed after all? What if we weren’t so stressed in our 20s? What if we weren’t feeling middle-aged in our 30s and 40s? What if, in our 50s, we wanted to reinvent ourselves and couldn’t think of a single reason why we shouldn’t? What if, in our 60s, we weren’t fretting about leaving a legacy but beginning one?

      What if we didn’t have to worry that the clock was ticking? And what if I told you that soon—very soon, in fact—we won’t?

      Well, that’s what I’m telling you.

      I’m fortunate that after thirty years of searching for truths about human biology, I find myself in a unique position. If you were to visit me in Boston, you’d most likely find me hanging out in my lab at Harvard Medical School, where I’m a professor in the Department of Genetics and codirector of the Paul F. Glenn Center for the Biological Mechanisms of Aging. I also run a sister lab at my alma mater, the University of New South Wales in Sydney. In my labs, teams of brilliant students and PhDs have both accelerated and reversed aging in model organisms and have been responsible for some of the most cited research in the field, published in some of the world’s top scientific journals. I am also a cofounder of a journal, Aging, that provides space to other scientists to publish their research on one of the most challenging and exciting questions of our time, and a cofounder of the Academy for Health and Lifespan Research, a group of the top twenty researchers in aging worldwide.

      In trying to make practical use of my discoveries, I’ve helped start a number of biotechnology companies and sit as a chair of the scientific boards of advisers of several others. These companies work with hundreds of leading academics in scientific areas ranging from the origin of life to genomics to pharmaceuticals.⁷ I am, of course, aware of my own labs’ discoveries years before they are made public, but through these associations, I’m also aware of many other transformational discoveries ahead of time, sometimes a decade ahead. The coming pages will serve as your backstage pass and your front-row seat.

      Having received the equivalent of a knighthood in Australia and taken on the role of an ambassador, I’ve been spending quite a bit of my time briefing political and business leaders around the world about the ways our understanding of aging is changing—and what that means for humanity going forward.⁸

      I’ve applied many of my scientific findings to my own life, as have many of my family members, friends, and colleagues. The results—which, it should be noted, are completely anecdotal—are encouraging. I’m now 50, and I feel like a kid. My wife and kids will tell you I act like one, too.

      That includes being a stickybeak, the Australian term for someone who is overly inquisitive, perhaps derived from the currawong crows that used to punch through the foil lids of the milk bottles delivered to our homes and drink the milk out of them. My old high school friends still like to tease me about how, whenever they came over to my parents’ house, they would find me pulling something apart: a pet moth’s cocoon, a spider’s curled-up leaf shelter, an old computer, my father’s tools, a car. I became quite good at it. I just wasn’t very good at putting these things back together.

      I couldn’t bear not knowing how something worked or where it came from. I still can’t—but at least now I get paid for it.

      My childhood home is perched on a rocky mountainside. Below is a river that runs into Sydney Harbor. Arthur Phillip, the first governor of New South Wales, explored these valleys in April 1788, only a few months after he and his First Fleet of marines, prisoners, and their
