Warren Buffett is famously known for buying sausage patties at McDonald’s every morning. He once said that a quarter of his daily calories come from Coca-Cola. He barely exercises. Charlie Munger wasn’t much different. He loved ice cream and read books while eating peanut brittle. No workout routine to speak of.
And yet, Buffett turns 95 this year. Munger lived to 99. By any modern standard of health, this makes no sense. The average American man lives to 76.
No diet. No exercise. No disciplined lifestyle to mention. And yet these two men may go down as the longest-lived investors in history. Which raises a genuine question: is there something about value investing that keeps you alive longer?
Was It Genetics?
The first instinct is to blame, or credit, their genes.
Buffett’s case is mixed. His mother, Leila Buffett, lived to 92. His sister, Doris Buffett, also died at 92. There’s clearly something on the maternal side. Research on longevity has long pointed to a connection between a mother’s lifespan and her son’s. Mitochondrial DNA passes exclusively through the maternal line and appears to influence cellular energy production and the rate of aging. But his father, Howard Buffett, died at 60. Genetics alone can’t carry the full explanation.
Munger’s case is more striking. His father, Alfred Munger, died at 66. His mother, Florence Munger, at 78. Munger outlived his father by 33 years and his mother by 21. This isn’t a man who won the genetic lottery. Something else was at work.
Both men drew the short straw on paternal genetics. Neither had a father who lived past 70. Yet they both reached the far edge of human longevity. There’s something beyond the DNA.
The People Who Removed Stress
Chronic stress kills. The research on this is not subtle. When cortisol floods the body over long periods, the immune system degrades, cardiovascular risk climbs, and cellular aging accelerates. Some researchers argue that chronic stress is more damaging than smoking.
The more interesting question is: when does stress become chronic? The answer, consistently, is when people lose control over their own lives. When you do work you didn’t choose. When someone else sets the standard by which you’re judged. When the external world, a boss, a client, a performance review, holds the power to determine your worth.
Look at Buffett and Munger’s lives through that lens, and something remarkable emerges. Both men eliminated that structure earlier than almost anyone.
In 1956, Buffett started a partnership, pooling money from family and friends. Returns were strong. Capital flowed in. His reputation grew.
Then in 1969, he shut it all down. He cited an overheated market and a scarcity of ideas that fit his approach. He returned every dollar to his investors.
From that point forward, he operated only through Berkshire Hathaway. If you wanted exposure to Buffett’s thinking, you bought the stock. You didn’t sign an agreement. You didn’t get a quarterly report with a benchmark comparison. You just owned shares in a company, the same way you’d own shares in any other.
This matters enormously. A traditional fund is structurally vulnerable to its clients. When returns disappoint, redemptions come. Managers are forced to sell positions they’d rather hold. The business model itself creates pressure to perform on someone else’s timeline.
Having covered financial markets in Korea for many years, I’ve watched this dynamic play out up close. Korea has no shortage of self-made investors who built their own asset management firms. People who started as individual investors, compounded extraordinary returns, and eventually launched boutique funds with hundreds of millions under management. They are, by any measure, successful. And almost without exception, they are under enormous stress. Client service. Benchmark pressure. Reputation management. Owning the firm doesn’t protect you from any of it.
Buffett solved this by changing the model. Berkshire runs on permanent capital: insurance float, subsidiary cash flows, retained earnings. There are no redemptions. No quarterly performance reviews. No clients to call back. Warren Buffett sits in a small office in Omaha and reads. That is, more or less, the job.
The 1969 decision wasn’t just a change in investment strategy. It was a structural elimination of the primary source of stress in his professional life.
The Capitalist, Properly Defined
There’s a useful distinction that gets lost in translation, especially for those of us from cultures that treat hard work as the highest virtue.
In Korea, where I grew up and spent most of my career, the professional ideal has long been the credentialed expert: the doctor, the lawyer, the engineer. America has always had a different hierarchy. The highest status belongs to the person who owns the machine, not the one who operates it.
Buffett is not a fund manager. His title is CEO, and that title is accurate. He owns Berkshire Hathaway. He owns stakes in Coca-Cola, Apple, GEICO. His income does not depend on managing anyone else’s money. He is, in the fullest sense, a capitalist.
Think of him as a landlord of the stock market, except the analogy breaks down quickly in his favor. Real landlords deal with tenants, repairs, property taxes, vacancies. Buffett reads annual reports and occasionally makes a phone call. His building keeps appreciating while he sits quietly inside it.
What separates Buffett from other billionaire CEOs is not his wealth. It’s that his performance is evaluated by no one but himself. He and Munger built a system at Berkshire that blocked external judgment. No external benchmark ruled their days. And the results speak for themselves. From 1965 to 2024, Berkshire compounded at 19.9% annually. The S&P 500 managed 10.4%.
Munger’s Inversion: If You Can Avoid It, Avoid It
Munger’s core intellectual habit was inversion. Rather than asking how to succeed, he asked how to fail, then avoided those paths with discipline.
He applied this to investing. Instead of hunting for the best stocks, he spent more energy identifying which ones would collapse. Bad management. Misaligned incentives. Structurally weak industries. Remove all of that, and what remains tends to be worth owning.
Buffett framed his own edge in similar terms: the reason he invests well isn’t high intelligence. It’s that he avoids doing stupid things.
Both men applied this to life itself. They thought less about who to spend time with than about who to avoid. Less about what to pursue than what to eliminate. Munger put it plainly:
“Avoid crazy at all costs. Crazy is way more common than you think. It’s easy to slip into crazy. Just avoid it, avoid it, avoid it.”
Their investment philosophy and their life philosophy were the same thing. Not addition, but subtraction. Chronic stress, unwanted obligations, the wrong people, the wrong environments. Gone.
This kind of freedom requires money, obviously. But money alone doesn’t produce it. Plenty of wealthy people spend their lives chasing the wrong things, performing for audiences they don’t respect, accumulating stress alongside their assets. The system has to be designed. And most people, even with the resources to design it, never do.
Outside the Hedonic Treadmill
One of the most striking facts about both men is how little they spent.
Buffett still lives in the Omaha house he bought in 1958 for $31,500. Munger lived in the same home for decades. Neither man built a compound in Malibu, bought a private island, or commissioned a Dubai-style palace, though each could have done so without noticing the expense.
This is often framed as admirable frugality. I think that misses the point. They weren’t restraining themselves. They genuinely didn’t want those things.
The hedonic treadmill is a well-documented psychological phenomenon. We adapt to improvements in our circumstances, and our baseline happiness returns to where it started. The upgrade becomes the new floor, and the floor always needs upgrading. Luxury doesn’t satisfy. It resets the threshold for what counts as enough.
Buffett and Munger never stepped onto that treadmill. Their reference point stayed low. Which meant that a Coke and a hamburger could still produce genuine pleasure. That’s not a trivial thing. Contentment that doesn’t require escalation is one of the rarest and most durable forms of wealth.
Their fortune grew astronomically, but not because they were trying to spend it. Watching a business compound, watching a judgment proven right by the market over years, that was the pleasure. Anyone who has spent time among serious investors will recognize this. The real satisfaction doesn’t come from the money. It comes from the moment the market confirms what you saw before anyone else did. That is the game Buffett and Munger were playing. And it never got old.
Living on Their Own Terms
The simplest summary of both lives is this: they built structures that let them do exactly what they wanted, and nothing else.
“Doing whatever you want” sounds irresponsible in cultures that prize discipline and duty, and I say this as someone who spent years in a newsroom where the ethic was relentless output. But Buffett and Munger’s version of freedom wasn’t laziness. It was the product of deliberate design, built over decades.
When Buffett dissolved his partnership in his early 40s, his stress level dropped and largely stayed low for the rest of his life. He became globally famous in his 60s, not because he worked harder, but because he had spent decades doing exactly what he was built for, without interference.
They were exceptional at removal. Obligations they didn’t want. People who didn’t fit. External standards they didn’t believe in. Strip all of that away, and what remained was the work they loved and the simplicity they preferred.
The irony is complete. The two men who built one of the greatest fortunes in American history found their daily happiness in the most ordinary things. A newspaper, a phone call, a hamburger, a Coke in a small office in Nebraska.
Their money compounded. Their contentment did too. And perhaps that second kind of compounding was the more important one.
