Wrongevity

Bryan Johnson has spent millions of dollars trying not to die. He takes a hundred pills a day. He eats the same meals every day. He goes to bed at 8:30 PM. He has undergone plasma transfusions from his own son, which the FDA has said are without proven benefit and potentially harmful. He employs a team of thirty doctors who monitor everything from his epigenetic age to his nighttime erections. He has built what is arguably the most rigorous, most expensive, most obsessively tracked longevity regimen any human being has ever attempted.

And he will almost certainly die within a standard deviation of the normal male lifespan.

Maybe he gets to 85. Maybe 90. The average American male life expectancy is 77. Johnson is clearly in excellent health, and the basics of his protocol, sleep, exercise, a clean diet, caloric restriction, are well-supported by evidence. Those things probably will add years. But here's the uncomfortable truth that the longevity industry does not want to discuss: the marginal gains from everything beyond sleep, exercise, and nutrition are vanishingly small. The exotic supplements, the NAD+ infusions, the hyperbaric chambers, the off-label prescription drugs, the stem cell treatments, the biological age clocks that promise to tell you how fast you're aging, all of it sits on the flat part of a diminishing returns curve.

Johnson is not the scam. He's the existence proof of the scam's ceiling. If the most resourced, most disciplined, most data-driven longevity enthusiast on earth is maybe buying himself a few years, what exactly is the $60,000 light bed at the Miami longevity clinic doing for you?

Where grift lives

Grift lives in the gray areas. Anywhere outcomes are hard to measure, time horizons are long, and causation is difficult to establish, you will find people selling things that don't work. This is not a conspiracy theory. It's just economics. When the feedback loop between intervention and outcome is weak, the signal that separates real value from noise gets attenuated (if you've read product jamming this should sound familiar). And when the signal is weak, the market fills with noise.

Longevity is the ultimate gray area. The outcome you're measuring, lifespan extension, takes decades to observe. You can't run a controlled experiment on a single person. You can't isolate variables when someone is simultaneously taking metformin, rapamycin, a dozen supplements, doing caloric restriction, sleeping eight hours, and exercising daily. And the proxy metrics that the industry has adopted, epigenetic clocks, biological age scores, telomere length, are themselves poorly validated. The pioneer of one of the most widely used epigenetic clocks has publicly stated that these tools are imperfect estimates, not direct measures of aging, and that they are being misused by people claiming dramatic age reversal.

This measurement vacuum is where the money flows. A survey of 82 longevity clinics worldwide found that over a third offer stem cell treatments with no evidence of lifespan benefit. Most are prescribing drugs off-label for aging, conditions for which those drugs were never tested. Clinics routinely position themselves as wellness providers rather than medical facilities to avoid regulatory oversight. Annual memberships run from $10,000 to over $100,000. The treatments on offer, NAD+ infusions, chelation therapy, exosome injections, IV vitamin cocktails, have not been proven in large-scale human trials to slow aging.

The structural problem is clear. The longevity field has no validated outcome metrics, no regulatory framework, no standardized biomarkers, and no consensus on what it even means to "treat" aging (the FDA does not classify aging as a disease). Into that void rushes a market that is, as one longevity researcher put it, dominated by medical influencers rather than scientists.

The diminishing returns curve

Here's the thing about the product axes framework applied to human longevity.

The core product is health. The core value proposition, being alive and feeling good, is as proven as anything that exists. Nobody needs to validate demand for being healthy. What the longevity industry claims to do is shift the product along the axis of duration: make you live longer, and make you healthier for longer.

The problem is that this axis has brutally diminishing returns.

The first moves along the duration axis are massive. Clean water, sanitation, antibiotics, vaccines, basic nutrition. These interventions took average human lifespan from 35 to 75 in roughly a century. The next moves are meaningful but smaller: managing chronic disease, reducing smoking, improving cardiovascular care. These push life expectancy from 75 toward 80.

After that, the curve flattens dramatically. From 1950 to 2010, life expectancy at birth in the US increased by about 65 days per year. From 1900 to 1950, it increased by 146 days per year. We are running faster to move slower. And the interventions being sold by longevity clinics sit at the very far right of this curve, where the marginal gains are smallest and the costs are highest.

This is the fundamental issue. Taking a walk every morning and drinking water will do more for most people's lifespan than any supplement stack a longevity clinic can sell them. Going to bed at a consistent time and eating vegetables will do more than rapamycin. Not smoking will do more than NAD+ infusions. The things that actually move the needle on human lifespan are boring, free, and well-established. The things the longevity industry is selling are expensive, speculative, and operate on the flattest part of the curve.

Bryan Johnson's own protocol proves this accidentally. His most impactful recommendations, the ones he leads with on his website, are sleep, nutrition, exercise, community, and avoiding addictive substances. Everything else is marginal. He knows this. His public-facing protocol is basically a list of things your grandmother already knew, wrapped in $35 olive oil and biological age testing.

The real opportunity cost

Here's where this gets genuinely important, and why I find the longevity industry frustrating beyond just the grift.

Every dollar spent chasing marginal lifespan gains for people who are already healthy is a dollar not spent on the people who are still stuck on the steep part of the curve.

There are 133 million Americans living with at least one chronic condition. These are people managing diabetes, hypertension, heart failure, COPD, autoimmune disorders, often several at once. They are not on the flat part of the diminishing returns curve. They are on the steep part, where interventions can produce massive gains in both lifespan and quality of life. Better medication management for a diabetic patient. Consistent blood pressure monitoring for someone with hypertension. Coordinated care for a person managing three conditions that nobody is connecting. These are not speculative interventions based on animal data. They are proven, evidence-based, and dramatically underdelivered.

The longevity industry's implicit argument is that the frontier of human health lies in extending the lifespan of the already-healthy. That the most important work is happening at the top of the curve, pushing the ceiling. This is wrong. The most important work, and the largest opportunity, is at the bottom of the curve, where the ceiling has already been proven and millions of people can't reach it.

From a pure learning standpoint, this is also where the science gets done. If you want to understand the fundamental mechanisms of aging, inflammation, cardiometabolic dysfunction, and cancer, you learn more from a massive sample of patients managing chronic conditions than from a handful of wealthy biohackers taking supplements. Chronic disease management generates the data. It reveals the biomechanics that underlie pathology. It produces the sample sizes that power real discovery. Giving zinc to rich people does not.

The longevity industry is optimizing at the margin while the mean is still broken. It is selling speculative axis shifts to people who have already captured most of the available gains, while ignoring the population where proven axis shifts would produce the largest returns.

What would actually matter

If you applied the product axes framework honestly to human health, you would not start with longevity. You would start with accessibility, continuity, and cost, the axes that keep 133 million chronically ill Americans from getting the care that is already proven to help them.

You would build systems that make chronic disease management continuous rather than episodic. You would make care accessible without requiring an appointment three weeks from now at a location across town during business hours. You would make costs predictable and low enough that people don't have to choose between their medication and their rent. These are the axes where the product sits at a terrible position, and where a large-magnitude shift would produce enormous gains in both individual health and population-level understanding of disease.

That's the steep part of the curve. That's where the returns are.

The longevity industry has it backwards. The path to understanding how humans live longer and healthier does not run through the supplement stacks of the 1%. It runs through the millions of people whose chronic conditions are being managed poorly, or not at all, right now. Improve their care, learn from their data, close the loop between intervention and outcome across a massive and diverse population, and you will learn more about what drives human health than any biohacker's protocol ever will.

The scam of longevity is not that the science is fake. Some of it is real and promising. The scam is the allocation of attention and resources. It's the implicit claim that the frontier of human health is at the far right of the curve, when the largest gains, the most important science, and the biggest market are all sitting at the left, waiting for someone to care enough to build for them.

My recommendation, for whatever it's worth from someone who had to make peace with this earlier than most: accept the limitations of human life. Stop trying to outrun the thing that makes life valuable in the first place. The longevity industry is built on the terror of death, and it sells the fantasy that enough money and enough data and enough supplements can make that terror go away. They can't. Death is not a bug in the system. It is the system.

What we can do, what actually matters, is make the time people have as good as possible. Help the person managing three chronic conditions feel better today. Help the patient who can't get an appointment get seen this week. Help the family that's drowning in medical bills afford their medication this month. That's the work. That's the frontier.

Gandalf said it better than I can: "All we have to decide is what to do with the time that is given us."

Spend it wisely. Spend it on the people who need it most.
