Fighting Death Or Living Intentionally?

Bryan Johnson once paid for continuous tracking of the duration and quality of his nighttime erections as a health indicator connected to aging. He has spent years taking more than a hundred pills a day , eating precisely controlled meals, going to bed early, and running an almost continuous stream of medical tests.

This year, he revealed that, despite all of it, he had been living with an autoimmune disease that went undiagnosed for years: autoimmune gastritis. “My stomach is eating itself,” he wrote on X.

He had low ferritin for eleven years without anemia. “We continually tried to raise my iron levels with food and supplementation but nothing would work.” An upper endoscopy and stomach biopsies eventually revealed the cause.

At first glance, this seems like an embarrassment for a man trying to defeat aging. But that misses the more interesting problem.

You can spend enormous amounts of money reducing health risks without gaining control over what your biology does next.

Most of us already worry about our health in the same ways, just with less money and fewer resources.

Consider the person who spends the last forty minutes of every night reviewing their Oura or Whoop data. Their sleep score is 79. Their resting heart rate is two beats higher than last week. Their recovery numbers have dipped. They compare the numbers with last month and go to bed slightly disappointed in themselves. The next morning, they move their bedtime earlier, change something about their routine, and still feel like they aren’t doing enough.

Wanting to live longer and wanting to feel in control of your health are not the same thing.

You can reduce health risks without controlling what happens next

It would be easy to see Johnson’s diagnosis as proof that all the money and effort haven’t worked. A man who spends millions each year trying to stay healthy and slow aging still develops a condition he didn’t know he had.

But that line of thought misses the more interesting problem.

Autoimmune gastritis isn’t simply a consequence of how someone lives. It’s an autoimmune condition in which the immune system attacks cells in the stomach that help with digestion and nutrient absorption. It can interfere with iron and eventually vitamin B12 absorption, and early on, it can be difficult to detect.

Johnson had low ferritin for 11 years, even without anemia. Autoimmune gastritis can remain undetected for years. Iron deficiency can appear before the better-known B12 deficiency, and the loss of stomach acid can make oral iron less effective. That helps explain why his low ferritin persisted despite efforts to raise his iron levels.

In a cohort of 291 patients , researchers found that the median delay from the first clues to diagnosis was 14 months; more than a quarter waited three years or longer. Johnson’s eleven-year history was far longer than that.

Persistent low iron eventually led to more tests. Johnson wasn’t ignoring the problem. Even with unusually close monitoring, it took a long time to find out what was actually happening.

None of this means our choices don’t matter. What we eat, how much we exercise, whether we smoke, how much we sleep, and whether we get appropriate medical care all affect our health.

But none of that gives us complete control over what happens next.

Your decisions influence probabilities. They do not guarantee outcomes.

But there’s an uncomfortable side to this. If you have the money and information to reduce a risk and choose not to, your choices clearly matter. We do have some responsibility for our health. The difficult part is knowing where that responsibility ends.

We all like the idea that if we do the right things, we’ll get the right result. Health is one of the areas where that belief eventually runs into reality.

Some biological problems are not failures of discipline

If someone smokes for 30 years and develops lung disease, we can point to a clear risk factor. If someone never exercises and develops heart problems, we have an obvious behavior to point to.

But when someone eats well, sleeps eight hours, exercises regularly, and still develops an autoimmune condition, there is no obvious behavior to blame.

Some biological problems are simply not failures of discipline.

Someone can make excellent decisions and still develop cancer, an autoimmune disorder, or a genetic vulnerability they never knew existed. Healthy behavior still matters. It improves your odds, but it does not guarantee the outcome.

This is where extreme measurement can start creating its own problems. The more closely you measure your health, the more numbers you have to think about. Those numbers can make you feel like you have more control. Once you measure hundreds of markers, every change becomes another decision: retest, intervene, or ignore. You get more information about one problem, but you also get more things to think about.

And knowing more isn’t always better. If a test finds something you can treat early, that knowledge can be valuable. But what if it finds a risk you can monitor but not eliminate? You may now have years of knowing that something could go wrong without having much you can do about it.

Before you measure something, you can say, “I didn’t know.” After you measure it, you may feel responsible for doing something about it. And when you’ve been measuring your health for long enough, you can start to believe that if something goes wrong, you simply didn’t do enough.

That’s where health optimization becomes exhausting.

A useful test is whether the next measurement or intervention changes a decision you would actually make. If a sleep score of 79 leads you to go to bed earlier and you feel better the next day, the tracking is serving a purpose. If the same score sends you into an hour of research, another wearable comparison, and a vague sense that you have failed, the tracking may be creating more stress than it’s helping you manage.

But there’s another problem: sometimes the extra monitoring really does help. Johnson’s persistent low ferritin eventually led to a diagnosis. The same behavior that can become excessive can also uncover something important.

The difficulty is knowing which situation you are in.

It’s easy to start with something sensible and gradually spend more time trying to make sure nothing goes wrong.

Money can help you find problems. It can’t control the outcome

The $2 million figure matters because it gave Johnson something most people don’t have: the ability to keep looking when the usual explanations didn’t make sense. His money didn’t just buy supplements and treatments. It gave him access to more testing, more specialists, and more chances to find an answer.

That advantage is real. Persistent low ferritin eventually led to the tests that uncovered his autoimmune gastritis. But finding a problem is not the same as controlling it. Even with extensive monitoring and resources, it took 11 years to find the cause of his low ferritin.

Money can help you understand your biology better, but it can’t control what your body does.

And this is where the argument gets harder. If more testing can uncover something that might otherwise be missed, why would you stop looking? The fact that money cannot guarantee an outcome doesn’t mean extra resources are useless. They can buy earlier answers, and sometimes an earlier answer changes what happens next.

The point is not to decide whether Johnson’s routine is ridiculous. Most of us do not need to decide whether he’s right about everything. We need to notice when trying to improve our health stops improving our odds and starts taking over our lives.

Trying to live longer can make us think about death more.

The more you think about living longer, the more you can end up thinking about death.

That’s not a criticism. If you want more time, you naturally start thinking about what could take that time away.

But if you’re serious about living as long as possible, you can end up paying a lot of attention to the things that might shorten your life. A symptom can make you start wondering if something is wrong. An unusual blood test result gives you something else to worry about. Even a slight change in your sleep can have you looking for an explanation.

Spending an hour exercising because you want another healthy decade is probably a reasonable use of your time. Spending another hour checking your health data, researching supplements, worrying about a result, and trying to figure out whether your exercise routine is really optimal is something else entirely.

At some point, you’re no longer simply protecting your health. You’re using part of your life to manage the possibility of losing your life.

It’s surprisingly easy to start with a sensible goal and gradually let it take up more of your attention than you intended.

The danger isn’t caring about your health. It’s forgetting what health is supposed to support.

Your time is limited. So is your attention. Every hour spent monitoring a possible future problem is an hour that cannot be spent doing something else.

The question isn’t whether health deserves attention. It’s whether you’re giving it so much attention that you have less time for the life you’re trying to protect.

There’s also a difference between wanting more years and wanting more healthy years. Someone might willingly spend more time monitoring their health if it gives them a better chance of staying healthy for another decade.

Another person might decide that spending less time worrying about their health is worth accepting that they can’t control everything that happens to their body.

What happens when preserving your life becomes one of the main things you do with it?

Suppose longevity research eventually becomes much more effective than it is today. Suppose medicine becomes extraordinarily good at delaying age-related disease.

That would be an incredible achievement.

And I’m not sure there’s anything wrong with being extremely serious about it. If spending more time monitoring your health gives you a better chance of being alive and healthy for another 20 years, someone could reasonably decide that the trade-off is worth it. What feels like too much to one person may be exactly the right amount of attention to another.

But there’s a question I want to ask: What happens when preserving your life becomes one of the main things you do with it?

More life is valuable because it gives us more time for relationships, work, family, pleasure, discovery, and everything else we consider worth having. But the value of that time depends partly on what we do with it.

One person spends 80 years building relationships, raising kids, working on things they love, and occasionally eating food they were told to avoid. Another organizes their life around staying as healthy as possible for as long as possible.

Neither life can be judged by a health score. But if you extend your life by five years while spending much of those five years worrying about how to extend it by another five, something has gone wrong.

You wanted more life. You ended up spending more of your life trying to get it.

And it applies well beyond Bryan Johnson.

You don’t need a medical team and a $2 million budget to end up in the same place. You can spend hours every week worrying about food, sleep, exercise, weight, supplements, symptoms, or test results and still feel as if you aren’t doing enough.

The question is no longer just “How healthy am I?” It becomes “How much of my life am I willing to organize around staying healthy?”

Those are different questions.

Take care of your health without trying to control everything

You should still take care of your health.

Exercise, a reasonable diet, and appropriate medical testing can all improve your chances of staying healthy. Everyone gets sick eventually, but that doesn’t make those things pointless.

The point is that you can do everything right and still have things go wrong. Do the things that are likely to keep you healthier for longer. Just don’t expect them to give you complete control over what happens to your body.

• Get enough sleep.

• Exercise.

• Eat reasonably well.

• Don’t ignore persistent symptoms.

• Get appropriate screening.

• Use good medical care when you need it.

But don’t treat every imperfect number as something you need to fix. Don’t assume every abnormal result means you should be doing more. And don’t believe that if you remove enough risks, nothing bad will happen.

There’s a difference between taking responsibility for your health and believing you’re responsible for everything that happens to it. Johnson’s case makes that difference unusually visible.

His extensive monitoring appears to have helped uncover something that had been missed for years. His resources gave him the ability to keep investigating when the usual attempts to raise his iron weren’t solving the problem, and the eventual biopsies supplied an answer.

The condition wasn’t prevented, and it had gone undiagnosed for years. But the monitoring helped turn a long-standing laboratory abnormality into a diagnosis and a clearer path forward.

Both things can be true: intensive monitoring can uncover problems that might otherwise be missed, and it still cannot make the body predictable or obedient.

Detection is not the same as control. The difficult practical question is knowing when it makes sense to keep looking and when you’re simply trying to rule out every possible problem.

The lesson isn’t that trying to live longer is pointless, but that no amount of discipline can make your body completely predictable.

What you’re protecting your life for?

Bryan Johnson has said his goal is immortality by 2039. His goal may sound extreme, but the desire behind it is familiar: most of us want more time.

Most of us don’t have the money to pursue that desire on his scale. But we still want to stay healthy, avoid disease, and be around for the people and things that matter to us.

We count calories. We watch our sleep. We check symptoms online. We buy supplements. We schedule checkups. We worry about what we ate yesterday and what it might mean ten years from now.

There’s nothing wrong with caring about the future. The question is whether the future becomes so important that we stop paying attention to the present.

Taking care of your body should give you a better chance of being around for the people, experiences, and things that make life worth living. It shouldn’t become the main thing you spend your life doing.

Autoimmune gastritis didn’t prove Johnson’s experiment failed. It didn’t prove it succeeded either. It showed something harder to accept: you can devote extraordinary resources to understanding your body and still encounter something you couldn’t predict or prevent.

We should try to live longer. But we also have to decide how much of the life we already have we’re willing to spend trying to make sure we get more of it.

Are you protecting your life, or slowly turning your life into the project of protecting it?
