The FDA cleared the first human trial of partial reprogramming in February 2026.

By inducing Yamanaka factors this method reverses cellular age.

Here is what is actually happening, and why it matters beyond the eye disease it is targeting. 🧵

@AFitTrader Everything you want has to be built.
The relationship, the body, the career, the freedom. Nobody delivers it.
Most people spend their 20s waiting for their 30s.

I don't think there will be nearly enough new jobs.
However we can challenge the premise that humans need "obvious contribution to the economy" at all. The economy is a coordination mechanism for producing the things humans want.
If AI produces those things, the productive problem is solved. What remains is a distributional problem and a meaning problem.

On distribution: some form of dividend or UBI seems mechanically necessary, otherwise you get a winner-take-all aristocracy with restive masses. The big question is whether we solve distribution before the political economy breaks.

On meaning: need to develop cultural infrastructure for lives organized around something other than market production. Sports, religion, science, family, art, mastery, status competition, exploration. These aren't substitutes for jobs. They're what jobs were always a substitute for.

Just my 2 cents. I think the meaning question is the bigger one long term, but short term the distribution problem is the one that worries me. If we don't solve it, we're looking at massive civil unrest well before anyone gets to enjoy post-scarcity.

@rand_longevity I sure hope so! Strike an incurable one today and no amount of optimisation saves you.
Some cancers are already near-solved. Others are still a death sentence. Get screened often!

Every coach, doctor, friend, and manager who ever told you what you wanted to hear instead of what you needed to hear is on the pink line.

I don't remember where I found this, but its spot on.

[Methuselah @MethuselahLab]

Excellent breakdown and mostly agree, we need less hype and more science.

However, solving aging completely is not the target. Longevity escape velocity is. Each generation of therapies buys time for the next. We don't need a complete map of aging to start outrunning it.

Recursive self-improvement plus wet-lab data flywheels closes the gap iteratively. And predicting at what stage of AI we crack the full problem is genuinely impossible. We might need terawatts of compute in orbit before we can model the complete aging landscape.

[Methuselah @MethuselahLab]

All of this is correct. The complexity is very real and undersold even by people who understand it.

But the framing of "solve biology" is the wrong target. We don't need to solve it. We need AI systems that improve their own models faster than aging accumulates damage. Recursive self-improvement plus data flywheels from wet-lab feedback loops.

The goal isn't a complete map of biology. It's staying one step ahead of the clock long enough to catch longevity escape velocity. That's a much lower bar than solving biology.

Doing PCT more than once is not inherently bad.
The real driver of those risks is cumulative AAS exposure (total dose × duration × number of cycles + multi-compound use).
There is zero evidence that repeated, properly timed PCT cycles desensitize the HPTA or cause permanent shutdown.

@hotiiofficial Morning gym is elite.
No crowd, no waiting, the day runs better after.
Just eat some carbs before and hydrate properly.
I will take the quiet over the 6pm jungle every time.

@rand_longevity Electrolytes before anything else.

@BasedBiohacker Insert shameless plug 🙋‍♂️

Every night you sleep badly, you are slightly less efficiently taking out the trash.

Your gym membership is the most underrated cognitive intervention available.

[Methuselah @MethuselahLab]

We train for marathons.
We train for careers.
Nobody trains for being 80.

Most people spend more on coffee per month than on anything that might meaningfully extend their healthspan. Start doing the basics now.

A jellyfish called Turritopsis dohrnii can revert back to its juvenile state when stressed. Biologically immortal.

You are not your chronological age.
You are the sum of your sleep, your movement, your metabolic health, your inflammation load, and your stress exposure over decades.

[Methuselah @MethuselahLab]

We don't say "he died of old age" anymore because we got specific enough to name the actual cause.
Heart failure. Pneumonia. Organ failure. Every one of those is a mechanism. Every mechanism is a target.

[Methuselah @MethuselahLab]

Longevity is not a rich person's hobby.
Metformin costs $4 a month. Zone 2 cardio is free. Sleep is free. The basics are more democratized than almost any other area of preventive medicine.

[Methuselah @MethuselahLab]

Longevity science is not about living forever. It's about buying enough time that the next breakthrough isn't too late for you.

[Methuselah @MethuselahLab]

"Die young, as late as possible." That's the whole pitch.
