POSTS STORIES REELS TAGGED

On October 5, the Nobel Assembly honoured three scientists for their work on light-gated ion channels and optogenetics:

🔬 Peter Hegemann (Humboldt University, Berlin) studied how single-celled green algae sense light. His work traced it to light-sensitive proteins called channelrhodopsins.

⚡ Georg Nagel (University of Würzburg) showed that these proteins are ion channels that open in response to light. When he put them into other cells, those cells could be switched on with light.

💡 Karl Deisseroth (Stanford) put these channels into neurons. With a flash of light, scientists could now switch a specific brain circuit on or off within milliseconds. This created the field of optogenetics.

🔹 Vision first. An experimental optogenetic therapy has already given a man with blindness partial vision back. The eye is the testing ground, and the brain is next.
🔹 Precision neuromodulation. Instead of treating the whole brain with a drug, future therapies may target only the circuit that’s failing in memory loss, Parkinson’s or depression.
🔹 Beyond the brain. The same switch is being used to study metabolism, heart rhythm and insulin signalling, which are central to how we age.

As a clinician, I’ll be clear that most of this is still experimental. We aren’t treating patients with it yet. But the principle is the same one my practice is built on: find the exact mechanism before you intervene.

The future of longevity isn’t only about living longer. It’s about keeping the mind sharp, the body moving and the systems working for all of those years. 🌿

He makes a whole studio laugh every night. Rumie heard what was underneath.

WHAT RUMIE KNOWS · Episode 2: The Laughing Heart

The Huangdi Neijing names Joy as the emotion of the Heart. But it warns that joy pushed too far, joy performed rather than felt, scatters the Heart’s qi until there’s nothing left to hold it together.

He’s the funniest man on television. The audience roars, the countdown card reads two minutes, and he never misses a beat. Between tapings he drops by the clinic, cracking jokes all the way down the hallway and onto the sofa.

Then Rumie looks up, and his eyes burn red.

A paw rests on his chest. The joking stops. And behind the screen, a memory opens: a little boy dancing on a bed, doing everything he could to make the people he loved smile. That was the day he learned his job was to keep everyone happy. He never put it down.

Healing begins quietly, with tea, stillness, and the first honest tears he’s allowed himself in years. Underneath the performance was something no one had asked about: the boy who never got to rest.

When he steps back in front of the studio audience, he doesn’t reach for a punchline. This time, he tells the truth.

Sometimes the person making everyone else laugh is the one who most needs to be held.

Relaxed luxury, in red. ❤️ Co-presented by @benchtm

Last night for Red Charity Gala 2026 at The Peninsula Manila, my dear friend JC Buendia showed what decades of mastery look like once a designer stops proving anything and starts listening to the body.

There were bias cuts that move with a woman instead of holding her in place, and A-lines that let her breathe, sit, and actually enjoy her night. Heritage ran through the whole collection: the ease of the kimono, the discipline of the cheongsam and áo dài, and the soul of the terno, all reworked in black, ivory, and blush against a sea of red. He even sent out golden cranes, the old Asian symbol of longevity. This Longevity Architect noticed. 🕊️

JC asked why anyone would look beautiful without being able to enjoy it, and that’s the kind of luxury I believe in: beauty that’s comfortable, intentional, and given back to a good cause.

Bravo, JC. Grateful to have witnessed it. 🙏

I’ll be honest: I walked in not knowing much about Kim Soo Hyun. I walked out a fan. 💙 Hearing him sing “Dreaming” live, surrounded by people who never stopped believing in him, I finally understood the devotion. Seasons of storm don’t last forever. Here’s to his healing, his strength, and a comeback a hundredfold brighter. Count me in. 🙏✨

She came in for tea. Rumie smelled something she’d been carrying for years.

WHAT RUMIE KNOWS · Episode 1: The Jade Knot

The Huangdi Neijing teaches that anger with nowhere to go doesn’t simply fade. It settles in the body, tightens, and knots, often long before anything shows up on a scan.

It begins like any other morning in the clinic. Tea is poured, a new patient arrives, and Rumie is half asleep on the sofa. Then, mid-conversation, his nose lifts and his eyes turn jade green. He crosses the room, rests his paw on her chest, and she freezes. Something there has been waiting to be found.

What Rumie uncovers isn’t only physical. Behind the knot is a memory: a warm bakery, golden bread, and a man she never forgave. Every time she goes back, the anger rises and holds her in place.

Healing happens on two fronts. The body is supported with careful, personalized care. The heart has slower work to do: returning to the bakery one last time, reading the note she never opened, and finally letting the tears come. As she does, the knot loosens and becomes something else entirely, an endless knot, the old symbol of connection instead of constriction.

Twelve weeks later she walks back into the clinic carrying bread. And she isn’t alone.

Some of the heaviest things we carry were never in our hands. They were in our chest.

WHAT RUMIE KNOWS 🐾 Official Teaser MV

Some patients walk into my clinic with a diagnosis. Rumie, my toy poodle, notices it first. He can smell it.

What Rumie Knows is a limited 7-episode animated series about Rumie, me, and patients whose bodies are holding on to something they never said out loud.

Each episode is built on one of the Seven Emotions from the Huangdi Neijing, the 2,000-year-old foundation of Chinese medicine: joy, anger, worry, overthinking, grief, fear, and shock. In each story, one emotion takes root in the body. And in each story, a patient finds the way back through mindfulness, hormone balance, nutrients, peptides, and a very good dog.

Swipe through the teaser 👉

▶️ 1/3 · RUNNING ON EMPTY
A young professional working late in a glass tower. A traveler drifting between island lagoons. Two people going through the motions while their bodies quietly keep score.
“Every cell doing work, every cell doing work, while you just vibe.”

▶️ 2/3 · THE TURN
Rumie and I step in. From the lagoon to a sunlit park, a golden-hour beach to a night market full of lights, their bodies start to remember what feeling good feels like.
“Not a quick fix, it’s a daily reset.”

▶️ 3/3 · THE HEALING
A sunrise surf. A bonfire by the sea. A quiet night on a park bench with Rumie.
“It’s not just the cure, it’s the healing.”

🎵 Original song written for the series.
🎬 Episode 1 drops soon. Turn on notifications so you don’t miss it.

Your body is wise. Rumie already knows.

This is an animated work of fiction for storytelling and education, not medical advice. Diagnosis and treatment always start with a qualified physician.

Episode 12 — The Clock

The first epigenetic clock was built from data other scientists had already collected for completely different studies.

That’s the part of this story I keep coming back to. Horvath pooled thousands of publicly shared samples and found age written across nearly every tissue. And one result still surprises me: embryonic stem cells read close to zero, as if new life resets the count.

In practice, the science has moved on. Newer clocks like GrimAge and DunedinPACE don’t just estimate age, they track risk and how fast you’re aging right now. So which clock I order matters. I use it as a baseline, retest after meaningful change, and always read it alongside genetics and labs, never on its own.

Twelve episodes, twelve moments where someone looked closer. The next chapter is the one we write with our patients.

Episode 11 — The Islands

The first thing the Okinawa researchers studied wasn’t diet. It was birth records.

That’s what struck me making this episode. Before counting a single centenarian, Dr. Makoto Suzuki checked each one against Japan’s family registry. Pes and Poulain did the same in Sardinia, and found villages where men reached 100 almost as often as women, something almost unheard of anywhere else. Then came the harder finding: as younger Okinawans moved toward fast food and desk jobs, their longevity advantage faded. Same genes, different life.

I carry both lessons into practice. Verify before you believe, whether it’s a longevity claim, a trend, or a testimonial. And never assume genetics will do the work that daily life has to do.

Longevity isn’t inherited. It’s practiced.

Episode 11 - The Synthesis

What I admire about Vincent du Vigneaud is what his work proved beyond the lab bench. When his synthetic oxytocin went into clinical testing, it worked exactly like the hormone the body makes. That settled a question medicine had argued over for decades: a peptide’s power lives in its sequence. Get the order right and the body cannot tell the difference. He did the same with vasopressin, and years earlier he had helped work out the structure of biotin.

That idea is why I’m strict about where peptides come from. If sequence is everything, then purity, sourcing and compounding standards are everything too. A peptide with the wrong fold or a contaminant isn’t the same message. Before I prescribe, I want to know who made it and how.

The body only answers messages written correctly.

Episode 9 - The Silent Gene

What I admire about this story is how small the starting point was. In a lab at MIT in the late 1990s, Leonard Guarente’s team studied yeast, single cells on a dish, and found that an extra copy of one gene, SIR2, let them live longer. That gene belongs to a family called sirtuins, and the work linked them to NAD+, a molecule every cell uses to make energy and repair itself. It sparked one of the most talked-about fields in aging research.

The lesson I carry into practice is the difference between a discovery and a conclusion. Some later studies couldn’t reproduce the lifespan effect in other organisms, and human evidence for NAD+-based therapies is still developing. The science is real and promising. It just isn’t finished. That’s why I build protocols around what we can measure in each patient, and I’m honest about where the evidence stops.

Finding the switch was the first word. We’re still learning to read the rest of the sentence.
