Mortality

Don’t die. That’s the simple mission statement of Bryan Johnson, tech entrepreneur, who is on a mission to extend his life as long as possible. He is not alone in this quest. In fact, the preoccupation with longevity is everywhere. Entrepreneurs are using AI to crack the longevity code. Cities are vying to be the new “longevity hubs.”

Most of the longevity movement is not really about immortality but rather about extending life and limiting the damaging effects of aging. Of course, we all want longevity. The danger of Johnson’s obsessive approach is spending so much time trying to extend your life that you never quite get around to living it.

Indeed, keeping death close—even while pushing it as far into the future as we can—has many lessons to teach us about life…. Death can help us focus our attention on living our best life, because there’s nothing that can teach us more about how to live life than death. Death is the most universal experience, yet we will do anything and everything we can to curtain it off, to avoid dealing with the only plot twist that we know for sure will be in our story’s last act.

Here lies the crux of the error of those that see human beings solely as material beings, they have confused an immortal soul with an immortal body. As the philosopher Pierre Teilhard de Chardin put it, “We are not human beings having a spiritual experience. We are spiritual beings having a human experience.”

When we don’t allow death into our lives, we lose the clarity, perspective, and wisdom that only death can bring. That’s why psychiatrist Elisabeth Kübler-Ross called death the key to the door of life: “It is the denial of death that is partially responsible for people living empty, purposeless lives; for when you live as if you’ll live forever, it becomes too easy to postpone the things you know that you must do.”

In mid-March 2024, Daniel Kahneman flew from New York to Paris to unite with his wife and daughter. They spent days walking around the city, going to museums and the ballet, and savoring soufflés and chocolate mousse. Around March 22, Kahneman, who had turned 90 that month, also started emailing a personal message to several dozen of the people he was closest to.

On March 26, Kahneman left his family and flew to Switzerland. His email explained why: This is a goodbye letter I am sending friends to tell them that I am on my way to Switzerland, where my life will end on March 27.

Kahneman was one of the world’s most influential thinkers—a psychologist at Princeton University, winner of the Nobel Prize in economics and author of the international blockbuster “Thinking, Fast and Slow,” first published in 2011. He had spent his long career studying the imperfections and inconsistencies of human decision-making. By most accounts—although not his own—Kahneman was still in reasonably good physical and mental health when he chose to die.

Why did he end his life? One friend said, “I think Danny wanted, above all, to avoid a long decline, to go out on his terms, to own his own death. Maybe the principles of good decision-making that he had so long espoused—rely on data, don’t trust most intuitions, view the evidence in the broadest possible perspective—had little to do with his decision.

Another friend said, “My best guess is he felt he was falling apart, cognitively and physically. And he really wanted to enjoy life and expected life to become decreasingly enjoyable. I suspect he worked out a hedonic calculus of when the burdens of life would begin to outweigh the benefits—and he probably foresaw a very steep decline in his early 90s.”

Benedict Cumberbatch has played a superhero involved in some precarious situations, but it turns out the actor has also experienced an actual life-threatening situation in his past. He revealed that in 2004, he was with friends in South Africa when they were robbed and abducted by six men. Eventually, Cumberbatch and his friends were tied up and made to sit execution-style before the men finally fled.

Cumberbatch said of the experience, “It gave me a sense of time, but not necessarily a good one. It made me impatient to live a life less ordinary, and I’m still dealing with that impatience.”

He also explained how the harrowing encounter spurred him to try extreme things to get his adrenaline up. “The near-death stuff turbo-fueled all that,” he said. “It made me go, ‘Oh, right, yeah, I could die at any moment.’ I was throwing myself out of planes, taking all sorts of risks.”

“But apart from my parents, I didn’t have any real dependents at that point. Now that’s changed, and that sobers you,” he added, in reference to his wife and three sons. “I’ve looked over the edge; it’s made me comfortable with what lies beneath it. And I’ve accepted that that’s the end of all our stories.”

Paul Auster, a prolific novelist, memoirist, and screenwriter was described as a “literary superstar” and “one of America’s most spectacularly inventive writers.” But his life was haunted by tragedy and death. In 1961, a 14-year-old Paul Auster watched a friend die after being struck by lightning. Later, he lost one grandmother to a heart attack and another to A.L.S., a disease which Auster said left victims with “no hope, no remedy, nothing in front of you but a prolonged march towards disintegration.” Later there were the deaths of his mother and father; the passing of his 10-month-old granddaughter Ruby, and his son, Daniel, who overdosed in 2022.

Auster wrote that “the world was capricious and unstable, that the future can be stolen from us at any moment, that the sky is full of lightning bolts that can crash down and kill the young as well as the old, and always, always, the lightning strikes when we are least expecting it.”

Sadness permeated Auster’s work. After his death at the age of 77, his wife wrote, “Paul was extremely interested in the idea of the hero who is cast into a new world by grief. He used that device a lot: the stripped person. The person who has lost their most profound connections to the world.”

Harvard geneticist David Sinclair’s business pitch has remained largely the same: Aging can be slowed or reversed, and we are about to figure out how.

“A lot of my colleagues dislike that phrase, the reversibility of aging,” he told a roomful of longevity investors. “But I truly believe that, based on my lab’s research and now others, that aging can be reversed. If I can make one medicine that would change people’s lives, I’d be very happy.” Sinclair also has co-founded companies that sell directly to consumers products such as supplements and tests that purport to show one’s “biological age.” He has also helped raise more than $1 billion.

But according to a report in The Wall Street Journal, the investors have almost nothing to show for it. Four companies trying to develop longevity drugs have gone bankrupt or largely halted operations. Another four either haven’t yet tested their drugs or gene therapies in humans or have run only small-scale trials that make it difficult to know whether a drug will work.

Sinclair has drawn criticism from fellow scientists, who say he exaggerates the findings and implications of age-related research. The board of the Academy for Health and Lifespan Research, a group Sinclair co-founded and led, asked him to resign as president earlier this year after he was quoted as saying a dog chew sold by a company he co-founded reversed aging in dogs.

Possible Preaching Angles:

It looks like we’re still living in the reality of the Fall, that human beings will age, grow old, and eventually die. We are still mortal!

A New York Times article called it “The Most Important Conversation to Have Before You Die.” The article opens by stating:

“Instead of talking about politics around the Thanksgiving table this year, consider a less fraught topic: death. It’s something few of us want to think about, but death is a fact of life that we will all encounter, often first as a caregiver and then, inevitably, when we reach our own.”

According to the article, what is the most important conversation to have before you die? It’s not about your eternal destiny. It’s not about your relationship with God or how to face final judgment. Instead, “discussing what medical care you want to receive at the end of your life is one of the most loving things you can do for your family.” The article notes, “While death can be a scary subject to broach, you may be surprised by how you feel after.”

Possible Preaching Angle:

Death, Preparation for – Granted this is an important conversation to have before you die, but Christians believe that there are conversations that are far more important than that topic. How many of us will leave our comfort zone and talk to family members about eternity and what preparation should be made to face God? By approaching these discussions with love, humility, and a genuine concern for their spiritual well-being, we can plant seeds that may lead to life-changing decisions about faith and salvation.

Need some perspective on the brevity of life? Here's a God's-eye view of the earth: Check out this real-time map of births and deaths around the world.

In 1950, there were 2.5 billion humans. As of January 2025, there are nearly 8.1 billion people. In another 30 years, according to U.S. Census Bureau projections, there will be more than 9 billion.

Brad Lyon has a doctoral degree in mathematics and does software development. He wanted to make those numbers visual. So, he and designer Bill Snebold made a hugely popular interactive simulation map of births and deaths in the U.S. alone (as of 2024, population 337 million)—the population of which is on pace to increase 44 percent by 2050.

Possible Preaching Angles:

Birth; Death; Life, short - How many people will die in the next minute? How many will be born? How should these numbers motivate us? Think of each of them as a story, as a unique soul loved infinitely by God. This is an excellent starting point for a sermon on Easter, resurrection, and our mortality. Consider projecting the real-time map as a stunning visual illustration.

In the year 1909, seven-year-old Walt Disney was playing by himself in the backyard of his family's farmhouse. He decided to sneak up on a big brown owl, but when he grabbed it the owl panicked, Disney threw it to the ground and stomped it to the death. According to his biographers, that owl haunted him for years, and produced a morbid fear of death.

Disney’s first big hit as a young animator came when he was 26 years old, in a cartoon featuring Mickey Mouse. But he immediately followed up that success with a short feature titled “The Skeleton Dance,” which opens with a terrified owl perched in a tree followed by skeletons rising from their graves. Disney’s distributor complained, saying, “We don’t want this gruesome crap… More mice… More mice!”

This was a small sample of what was to come. One scholar said, “If Disney was a mouthpiece for an American way of life, the force of his voice depended on a curious obsession with death.” Virtually every one of his famous films focused on the subject, from Snow White to Pinocchio.

His personal life was focused on decline and demise as well. Disney’s daughter Diane said that Disney hired a fortuneteller when he was in his early 30s to predict when he would die. The fortuneteller predicted the age of 35. Disney distracted himself by workaholism and success. If he stayed busy, maybe he could distract both himself and the Reaper. He survived 35, but never forgot the prediction. Shortly before his 55th birthday, he knew that maybe he had misheard, and the fortuneteller had said 55, not 35.

“Most of us will live an amazingly long life and should not worry so much about dying young.” Those are the words of Jonathan Clements, 61, who wrote more than 1,000 personal finance columns for The Wall Street Journal between 1994 and 2015. Plan on living past 90 and save accordingly, he advised, when he wasn’t running marathons or riding bicycles.

In May of 2024, he saw a doctor about some balance issues. Two days later, he received a devastating cancer diagnosis. Scans revealed a golf-ball-size tumor on his lung, and the disease has spread to his brain, his liver and elsewhere. Anything beyond 12 decent months would be a victory. “I’m definitely on the clock here,” he said as we sat at his kitchen table this week.

Clements said, “The No. 1 thing money can do for us is to give us a sense of financial security, and the way it does that is not to spend it and to hang onto it.”

Possible Preaching Angle:

Clements did not know that there is only one source of true security, and it is not money. “God is our refuge and strength, a very present help in trouble” (Psa. 46:1).

The longevity business is booming. People are flocking to longevity meetings and taking compounds they hope will extend their lives. Investors are backing scientists researching techniques to reprogram cells to a younger state. Longevity influencers argue that if they can live long enough, scientific breakthroughs will keep them going indefinitely. “We are going to start to understand how to rejuvenate and revitalize ourselves. This is what science does,” said Dr. Peter Diamandis, a 63-year-old entrepreneur who runs longevity trips for investors.

But S. Jay Olshansky, who studies the upper bounds of human longevity at the University of Illinois Chicago, believes people shouldn’t expect to live to 100. He contends most will reach between 65-90. Olshansky said, “It’s basic biology. As people grow older, their cells and tissues accumulate damage. Breakdowns of one kind or another happen more frequently and get increasingly difficult to repair.”

Nobel laureate Venki Ramakrishnan explained the many reasons in his book, Why We Die. He doesn’t believe current interventions will dramatically extend lifespan. Techniques to reverse aging would have to help every system in the body, including the brain, over a long period.

In 1979 Dr. Ellen Langer, a Psychology Professor at Harvard, designed a weeklong experiment for a group of 75-year-old men. The men knew very little about the nature of the experiment, except that they would be gone for a week. When the men arrived, they were told that for the coming week they were to pretend it was 1959 (not 1979) the time when these 75-year-old men were only 55-years-old. They were told to dress and act like they did at that time. They were given ID badges with pictures of themselves in their mid-50s.

Over the course of that week, they were instructed to talk about President Eisenhower (as though he were still President) and other events in their lives that had happened at that time. They were to talk about their old jobs like they were working in them now, and not as if they had retired from them. Copies of LIFE magazine and the Saturday Evening Post from 1959 were displayed on coffee tables. Everything was designed to make them see through the lens of their 55-year-old selves.

Before this retreat the men were tested on every aspect of life that we assume deteriorates with age. By the end of the retreat most of the men had improved in every one of these categories. For example, they were significantly more flexible, had better posture, and even much improved hand strength. Their average eyesight improved by almost 10%, as did their performance on tests of memory. In more than half the men intelligence increased as well. Their physical appearance changed. Random people who did not know anything about the experiment were shown pictures of the men before and after the experiment and asked to guess their age. Based on these objective ratings the men were described as looking on average three years younger than when they arrived.

Professor Langer demonstrated that even when objectively nothing has changed about us, simply having a different mindset can powerfully shape our reality.

Possible Preaching Angle:

In Ephesians 4:24-5:2, the Apostle Paul observed that when a person adopts a new mindset, not because they have been tricked into a different way of thinking because of their surroundings but, based on the reality of being made new creations, they can experience a profound transformation.

Multiple New York Times best-selling author and documentary director Sebastian Junger had a near-death experience in June 2020. This was due to an unexpected abdominal hemorrhage, which he survived thanks to his doctors. This led him to explore the topics of death, near-death, and the afterlife in his 2024 book In My Time of Dying: How I Came Face to Face With the Idea of An Afterlife. After he had escaped death, Junger, a committed atheist, had several deep moments of reflection:

But I didn't die, and it made me wonder what this new part of my life was supposed to be called. The extra years that had been returned to me were too terrifying to be beautiful and too precious to be ordinary. A week after I came home, I found myself sitting at a window looking at a crab apple tree in the backyard. The branches were waving in the wind, and I had the thought that they'd be waving in exactly the same way if I'd died, only I wouldn't be here to see them. The moment would be utterly beyond my reach. Eventually [my wife] Barbara asked if I felt lucky or unlucky to have almost died and I didn't know how to answer. Was I blessed by special knowledge or cursed by it? Would I ever function normally again?

Junger flipflopped daily from wondrous thankfulness to existential dread:

Barbara said she couldn't take much more of me like this and made the excellent point that I had an opportunity to experience the insights of terminal illness without - almost certainly - having to pay the price. What was I learning? What could I come away from this with? My father had continued reading history books until the last weeks of his life. Would I keep practicing music if the news were bad? Reading? Running? What would be the point - but then, what's the point anyway?

Possible Preaching Angle:

Unbelievers are given an opportunity to come to faith by God, but sadly many hedge, delay, and then go back to their old ways, ultimately untouched by their experience.

In an interview with Danny Devito, actor Arnold Schwarzenegger despairs at the reality of death and wonders who’s to blame. When someone asked him what happens when we die, he said (curse words deleted):

Nothing. You’re 6 feet under. Anyone that tells you something else is a [...] liar. We don’t know what happens with the soul and all this spiritual stuff that I’m not an expert in, but I know that the body as we see each other now, we will never see each other again like that … When people talk about, 'I will see them again in heaven,' it sounds so good, but the reality is that we won’t see each other again after we’re gone. That’s the sad part. I know people feel comfortable with death, but I don’t. Because I will [...] miss [...] everything.

Schwarzenegger considers what that he’ll miss when he dies: “to have fun and to go to the gym and to pump up, to ride my bike on the beach, to travel around, to see interesting things all over the world.”

DEVITO: “Life! It’s the best!”

Schwarzenegger then wonders who’s to blame.

SCHWARZENEGGER: I tell you, there’s someone that mixed up this whole thing. Think about it. Who can we blame?

DEVITO: You mean that we don’t live forever?

SCHWARZENEGGER: Yeah. That we have to die.

DEVITO: That’s tough, man.

SCHWARZENEGGER: I don’t know what the deal is, but in any case, it’s a reality, and it truly [ticks] me off.

DEVITO: You don’t want to die.

SCHWARZENEGGER: No. What the […]? What kind of deal is that?

One-third of U.S. adults said they would probably or definitely take a drug to prevent or reverse graying if such a medication were approved, according to a poll of 9,000 people. Some endorse gobbling black sesame seeds and blackstrap molasses to give gray hair the brush off. Others take liquid chlorophyll or douse their hair in onion juice. In online forums, posts about reversing grays can draw hundreds of replies.

Humans have been trying to chase away gray for millennia. Clay tablets from the Assyrian Empire dated to the 7th Century B.C. mention using the gall of a black ox, cypress oil, licorice, and honey to turn gray hair black. Ancient Egyptians applied oil cooked with the blood of a black calf, according to the 3,500-year-old Ebers Papyrus. (Presumably, if it worked, we’d still be trying it).

Tech entrepreneur Bryan Johnson, who is spending millions experimenting on himself to slow aging, posted a YouTube video detailing his regimen to reverse hair loss and graying; the video has nearly 700,000 views.

Johnson, 46, uses two topical treatments. One contains an herbal extract that, Johnson acknowledges, has colored his hair. But he says something is reversing his grays. When he has looked closely at plucked hairs, he says color has returned to some of them. What is working? He isn’t sure. Johnson’s routine also includes more than 50 supplements daily and trips to a Honduran island for $25,000 gene-therapy injections.

On a recent episode of The Howard Stern Show, the “shock-jock” host asked his guest, music legend Paul Simon, questions about music, life, art, and anything else that came to mind. Stern rose to fame with his exaltation of immorality and self-adulation. At the end of the interview, Stern said:

Paul, just give me one last answer. You seem very wise. You’ve lived through everything. You’ve created great masterpieces. Is there a God? Because I need to know. I’m getting older. Is this it for me? Am I going to die and that’s it or am I going somewhere? And please answer it in a serious manner.

Simon responded,

This is my feeling about God or Creator. The planet that I’m living on is so beautiful and the universe is so awe-inspiring. If that is the work of a creator, I say, “Thanks so much. I really love your work on the universe. Excellent work, coming from me, Paul Simon, to you, I really dig what you’re doing.” If it turns out that there’s another explanation for creation, I’m still unbelievably grateful for my existence. I still think it’s amazing. If it turns out, I thought it was God but it’s some other explanation, it doesn’t matter to me ….

Then, Stern interrupted, “But it’s so cruel. We have this existence and then we have to disappear. It’s hard.”

Actress and former Seinfeld star (as Elaine) Julia Louis-Dreyfus has had moments when tragedy and comedy get put in a blender. Monday, September 18, 2017, was one of them. Louis-Dreyfus and the hit TV show Veep had triumphed at the Emmys the night before. By morning, her doctor was on the phone telling her she had cancer. The first thing she did after hanging up was double over with laughter.

She said, “I mean, it felt like it was written. It felt like it was a horrible black comedy. And then it sort of morphed into crying hysterically.” [But she was also] terrified. “You just simply don’t consider it for yourself, you know, that’s sort of the arrogance of human beings. But of course, at some point, we’re all going to bite it.”

Pastor John Yates III once worked for the British scholar and Bible teacher John Stott. Yates reflected on the time when Stott’s aging and disability started to slow Stott down. Yates says:

Stott spent the last 15 years of his life going completely blind. It began with a small stroke that knocked out the peripheral vision in his left eye, forcing him to surrender his driver’s license. And over the years that followed, this man who wrote more books during his lifetime than most of us will read in an average decade became unable to see the pages in front of him. But that wasn't all. His body grew increasingly weak. He needed more sleep. He was eventually confined to his bedroom.

I spent three years working closely with John when he was in his early 70s. I was in my mid-20s. It was absolutely exhausting. I've never been around another person with a capacity for work as fast as his. He was the most disciplined and efficient man I've ever known. But there he was, years later, now in his 80s and into his early 90s, with his mind as sharp as ever. But then he was unable to do much of anything, except to sleep, eat, and listen out his bedroom window for the call of a familiar bird.

Now I found this personally incredibly difficult to understand. Why would God allow a man like John to suffer the loss of precisely those faculties that made his life so meaningful and has worked so successful, if it just seemed cruel? It would have been better, I thought, for him to die or to suffer from Alzheimer's, because at least then he wouldn't have known what he was missing.

But then I finally begin to understand why John never seemed to complain. That's because God was giving him the gift of absolute dependence. God was showing him that he delighted to offer Stott a dependence on him.

We may not want to admit it but author Arthur Brooks is convincing when he writes to the effect that age-related decline will come much sooner than we think. We might make excuses for ourselves but our recall of names and places is not what it used to be. He writes:

By the time you are fifty your brain is as crowded with information as the New York Public Library. Meanwhile, your personal research librarian is creaky, slow, and easily distracted. When you send him to get some information you need—say, someone’s name—he takes a minute to stand up, stops for coffee, talks to an old friend in the periodicals, and then forgets where he was going in the first place. Meanwhile, you are kicking yourself for forgetting something you have known for years. When the librarian finally shows back up and says, “That guy’s name is Mike,” Mike is long gone and you are doing something else.

Some years ago, a frozen pizza company was trying to figure out an advertising campaign to bring attention to their product. They designed a series of humorous commercials where an individual was about to lose his life in some melodramatic fashion—in front of a firing squad, about to walk the plank, or a teenager who’d had a party while his parents were away for the weekend. In each case, they were asked, “What do you want on your tombstone?” to which the answer was “pepperoni and cheese” or some other pizza topping.

It was a risky ad since Americans don't want to hear about death. The company was trying to be funny with their name: Tombstone Pizza Company which originated in the Tombstone Tavern in Medford, Wisconsin. The tavern was across the street from a cemetery.

But seriously, if you requested a stone to be placed over your grave, what would you want on your tombstone?

For example, Ruth Bell Graham, the wife of evangelist Billy Graham, died in 2007 and had this chiseled into her tombstone, "End of Construction -- Thank you for your patience." She didn't pick a favorite Bible verse or a lofty quote from a famous leader. She humbled herself and admitted that her life had been "a work in progress" until she died.

Formerly the Religion Editor for the Atlantic, Sigal Samuel now writes about the future of consciousness, artificial intelligence, and neuroscience, and their "staggering ethical implications." She describes much of the hope for artificial intelligence as mimicking what Christianity and other major religions have been espousing for centuries. She writes:

Suppose I told you that in 10 years … you will live in a sort of paradise. You won’t get sick, or age, or die. Eternal life will be yours! Even better, your mind will be blissfully free of uncertainty — you’ll have access to perfect knowledge. Oh, and you’ll no longer be stuck on Earth. Instead, you can live up in the heavens.

The more you listen to Silicon Valley’s discourse around AI, the more you hear echoes of religion. That’s because a lot of the excitement about building a superintelligent machine comes down to recycled religious ideas. Most secular technologists who are building AI just don’t recognize that.

These technologists propose cheating death by uploading our minds to the cloud, where we can live digitally for all eternity. They talk about AI as a decision-making agent that can judge with mathematical certainty what’s optimal and what’s not. (It is) an endeavor that guarantees human salvation if it goes well, even as it spells doom if it goes badly.

Jack Clark, co-founder of the AI safety company Anthropic, recently wrote: “Sometimes I think a lot of the breathless enthusiasm for AGI is misplaced religious impulses from people brought up in a secular culture.”

Sigal Samuel summarizes the beliefs in this nutshell: "When we put all these ideas together and boil them down, we get this basic proposition:

• We may not have much time until life as we know it is over.
• So, we need to place a bet on something that can save us.
• Since the stakes are so high, we should ante up and go all in on our bet.

Silicon Valley’s vision for AI? It’s religion, repackaged
