The Protocol That Doesn’t Know My Zip Code

Tolstoy opened Anna Karenina with a line that’s often translated as: all happy families are alike, but every unhappy family is unhappy in its own way.

I think about that line more than I expected to when I listen to longevity podcasts, just flipped around.

The protocols that actually work tend to look similar once you strip away the branding: sleep, movement, real food, real relationships. It’s the protocols that fail for wildly different, deeply personal reasons, and almost nobody in this genre talks about why.

Most of what gets recommended in this space was built by and for a fairly specific kind of person: young, based in the Bay Area or somewhere similar, financially comfortable, without decades of wear on his body yet, and usually without a spouse’s schedule, a job with fixed hours, or kids to plan around.

I’m not that guy.

I’d guess most of the audience listening isn’t either, and yet the protocol arrives as if it were written personally for whoever’s listening.

The three-hour morning nobody has

A fair number of these routines assume a morning that stretches to two or three hours before any actual obligation starts.

Light exposure at sunrise. A cold plunge. A sauna session. A structured workout. A specific breakfast prepared from scratch.

If your day starts with checking markets before they open somewhere else in the world, or getting a spouse and kids out the door, or simply commuting somewhere at a fixed hour, that morning doesn’t exist.

Following the protocol anyway usually means cutting it down until it’s unrecognizable, or quietly giving up on it after a week. The second outcome is often worse than never starting, because now it feels like a personal failure instead of what it really was: a scheduling mismatch.

This is one reason I keep coming back to a question raised in my earlier piece on longevity podcasts: what happens when the person giving the advice is not the person receiving it?

The answer, I think, is that we tend to copy the visible parts of a protocol and ignore the invisible conditions that made it possible in the first place.

A body with thirty more years on the clock

The same problem appears when the variable isn’t time but biology.

Aggressive training advice, aggressive fasting windows, aggressive supplement stacks — all of it tends to assume a body that hasn’t accumulated three decades of joints, old injuries, and whatever quiet wear happened along the way.

What’s a reasonable stretch for a 32-year-old’s knees is not automatically reasonable for mine.

Nobody necessarily says this out loud in the episode, because the protocol is presented as universal, backed by a study that, if you check, was very often run on people half the age of half the audience listening to it.

That’s an important distinction.

Evidence can tell us that something worked in a particular population. It doesn’t automatically tell us that the same intervention will produce the same result in a different population, with a different baseline, different risks, and a different body.

In investing, I would never assume that a strategy tested on one asset, in one market, under one set of conditions, transfers perfectly to another simply because the chart looks similar.

Health deserves at least the same level of caution.

The team you don’t have

Then there is the infrastructure.

Bryan Johnson runs his protocol with a level of monitoring and medical support that most people simply don’t have. Bloodwork is tracked. Results are reviewed. Interventions can be adjusted. The whole thing operates more like an ongoing research project than a checklist someone follows between meetings.

That’s a legitimate approach for someone with the budget and infrastructure to run it that way.

But taking a protocol built around that level of supervision and applying it solo, based on a podcast summary, is not the same intervention with a smaller budget.

It’s a different, much riskier thing wearing the same name.

This is a mistake we make surprisingly often with health advice. We copy the intervention but leave behind the system that was supposed to make the intervention safe.

It’s like taking a leveraged investment strategy designed for a professional risk desk and deciding that the same strategy should work just as well in a personal brokerage account because the trades themselves are identical.

They aren’t.

The surrounding risk management is part of the strategy.

The protocol is not the product

There is another reason these routines are so easy to misunderstand.

The protocol is visible, but the person is not.

You can see the supplements, the fasting schedule, the workout, the morning light, the cold plunge. You can’t see the decades of accumulated health data behind the recommendation. You can’t see the person’s genetics, medical history, recovery capacity, financial freedom, or the team helping to interpret the results.

The visible checklist becomes the product. However, the context disappears.

And once the context disappears, people start asking the wrong question: Which protocol should I follow?

The better question is: Which part of this protocol contains an idea that makes sense for me?

That is a much more useful question because it allows the intervention to shrink or change without losing its underlying purpose.

Walking instead of the specific cardio format.

A consistent sleep window instead of reproducing an exact light-exposure sequence.

Strength training adapted to the body you actually have instead of copying someone else’s workout.

A simpler diet you can sustain instead of a perfect nutritional system you abandon after ten days.

The principle survives.

The protocol changes.

What I actually do with any of this now

I’ve started running new health claims through roughly the same filter I’d use before sizing a position:

What’s the actual evidence behind this?

Who was it tested on?

Does my situation resemble theirs closely enough that the result should transfer?

And then one more question:

What would have to be true for this recommendation to work?

That last question is the one I find most useful.

If a protocol assumes three free hours in the morning, a 30-year-old’s joints, and a private medical team — and I have none of those three things — the honest move is not to reject the entire idea.

It’s to take the underlying principle and rebuild it at a scale that fits an actual life.

This is, in a way, the same discipline I would apply to an investment thesis. I don’t need to reject a good idea because the original investor used more capital, had a different time horizon, or had access to information I don’t have.

But I also don’t pretend that copying the trade gives me the same position.

The conditions matter.

Health is no different.

None of this is a reason to tune the longevity genre out. Quite the opposite. There are plenty of useful ideas in it.

It’s a reason to ask one extra question before adopting any of them:

Built for who, exactly — and is that still true of me?

The Short Version

1. Most longevity protocols were built for a specific kind of person, and rarely say so.
2. A three-hour morning routine assumes a life without a job, a spouse’s schedule, or kids to get out the door.
3. Interventions tested on younger bodies don’t automatically transfer to older ones.
4. A protocol built around a private medical team becomes a different, potentially riskier thing when you follow it alone.
5. Take the underlying idea, not the exact protocol, and rebuild it at a scale that fits your actual life.

Before adopting any longevity protocol, ask one question: built for who, exactly — and is that still true of me?
