Hi Reader,

I was quoted recently in this Forbes article on Molecular You, which I'm particularly excited about because they're commercializing multi-omics testing!

It's still very early days, but this is the kind of technology that will bring longevity out of the wellness trap and into true scientific innovation.

In other news, I wanted to bring up a boring but important metric we seem to forget in longevity: blood pressure. If your blood pressure is >120/80, you've got an easy and critical goalpost to aim for. Controlling blood pressure can

Now let's move on to something exceptionally not boring...

What if your child were your clone?

In 1978, Louise Brown's birth made global headlines as the first "test tube baby." Today, 1 in 37 American babies is conceived through IVF—in Massachusetts, it's 1 in 16. Over 13 million humans now owe their existence to assisted reproduction.

But here's what's coming: within a generation, we might not need IVF at all. The same technologies promising extreme longevity are about to make human reproduction unrecognizable.

Your 150-Year-Old Skin Cell Is Fine, Thanks

Forget everything you've heard about needing "pristine young cells" for future cloning. ViaGen Pets routinely clones dogs from deceased elderly pets—taking cells post-mortem and creating healthy puppies. The cloning process itself (somatic cell nuclear transfer) reprograms any adult cell back to an embryonic state, essentially resetting its developmental clock.

This isn't theoretical. Over 2,000 dogs have been successfully cloned since 2005, living normal lifespans for their breeds. Barbra Streisand has two genetic copies of her Coton de Tulear. The technology works with cells from any age—it's just expensive ($50,000-$100,000) and ethically complex.

For longevity enthusiasts, this changes everything. But what about pregnancy itself?

The Robot That Makes Pregnancy Optional

China's Kaiwa Technology just announced a humanoid "gestation robot" with an artificial womb in its abdomen, targeting a 2026 prototype for under $14,000. While it sounds absurd, the underlying technology—ectogenesis—is already keeping premature lambs alive in plastic bags filled with synthetic amniotic fluid for weeks.

The trajectory is clear: full artificial gestation is coming. When it arrives, pregnancy becomes optional, not just for those who can't carry children but for anyone who prefers not to.

Genetic Immortality Isn't Perfect Immortality

Those cloned dogs reveal certain uncertainties: they're genetically identical but often have different personalities and health quirks (2.9% cleft palate rate, 25% sex reversal in some breeds). Early fears that Dolly had "old" telomeres proved overblown—cloned animals can have normal or even extended lifespans. But genes are a recipe, not a guarantee.

Epigenetics, that stubborn biological accountant, keeps meticulous records of every environmental influence. Your cloned organs might carry unexpected variations. Your preserved fertility might produce surprises. Biology resists perfect control.

The Timeline That Changes Everything

• 2026: First humanoid gestation robot prototype (claimed)
• 2027: Potential human trials for partial artificial wombs
• 2030s: Therapeutic cloning likely routine for organ replacement
• 2030s-2040s: Predicted longevity escape velocity by optimists

These technologies are converging just as the first generation that might live to 150+ enters their prime.

Hair Longevity: Where Science Meets the Next Beauty Frontier

The beauty industry has found its next obsession: making your hair "age" slower. But unlike many wellness trends, this one has surprisingly robust science behind it—even if the marketing sometimes runs ahead of the research.

The Science That Actually Works

UCLA researchers recently discovered PP405, a molecule that literally wakes up dormant hair follicles. In human trials, participants saw significant regrowth of thick, terminal hair after just a week of nightly application—results that outperformed traditional treatments.

But while you're waiting for PP405 to hit the shelves (we still have a few years of trials), research shows that a combination of targeted nutrition (e.g. iron and vitamin D), stress management, and maintaining scalp health creates better outcomes than any single intervention.

The Marketing Machine Revs Up

Enter the "skinification" of hair care—treating your scalp like facial skin with anti-aging serums, ceramides, and peptides. Brands like Kérastase and VEGAMOUR are launching "slow aging" lines, while fermented ingredients and microbiome-balancing formulas proliferate. The trend reflects genuine consumer demand for preventive care, but buyers should note: not all products have the clinical backing of something like PP405.

Here's what the hype doesn't tell you: true hair aging reversal is still on the lab bench, and it isn't always effective. That promising rapamycin treatment that partially reversed graying in lab studies? It didn't work for everyone. And genetics remains the strongest predictor of your hair's future—no serum can completely override your DNA.

Your Hair Longevity Action Plan

While we wait for PP405 to hit the market and stem cell treatments to mature, the evidence supports a practical approach:

• Stop bad habits like smoking, overheating hair
• Check labs: ferritin, vitamin D, thyroid if relevant
• Correct deficiencies and eat a protein-rich diet
• Manage stress and prioritize sleep
• Use gentle shampoos/avoid harsh chemicals
• Consider proven options (minoxidil, finasteride, spironolactone, microneedling, LLLT/red light, PRP)
• Be skeptical of “miracle” serums with little data (FYI biotin is likely unhelpful unless you have a true deficiency)
