Four days to build actual capacity. Designed by Dr Tam and , facilitated alongside and a small team of experienced practitioners.

The container: a 14th-century monastery in the mountains above Deià. Ancient stone, olive terraces, sea air, wild paths. The setting holds attention.

The work: breath, specific movement patterns, bodywork, nature immersion, sea swims, group dynamics. Four days of attuning. aligning. connecting. elevating.

Fuel matters. Meal timing, microbiome nourishment, nervous system support - all built into how we eat across the four days. It's part of the work, not separate from it.

BioHarmony®️ cuts through the noise. You learn physiology through your body, not theory. You learn how to regulate before you optimize. You experience what co-regulation actually means - in real time, with other people, held by skilled practitioners.

Capacity is presence. It's resilience. It's actually experiencing your life - your relationships, your work, the hard moments - without dysregulation taking over. It's joy and vitality, not just longevity.

These retreats are small by design. The work requires ratio and attention. Spaces fill fast.

The next BioHarmony®️ retreat in Deià begins on 29 October.

THE LONGEVITY MOLECULE THAT JUST LANDED IN YOUR SKINCARE

Mitophagy: your cells' own way of clearing out damaged mitochondria and renewing themselves from within. It's one of the most talked-about processes in longevity science - and it's just made the leap from supplements into skincare, with Urolithin A now formulated into Lancôme's new Absolue Longevity MD.

Why it matters: your skin's mitochondria power everything from collagen production to repair and renewal. Supporting that process at a cellular level is a different approach to ageing well than simply treating what's already visible on the surface. Urolithin A itself is backed by close to a decade of published human research - what's new here is seeing it formulated specifically for skin.
In collaboration with
- who’s oral mitopure supplement I also use.

The other half of the equation is mindset. At The Longevity Clinic pop-up at London, I joined and from “” to discuss how the way we think about ageing shapes how we actually age. Great skin was never just about what you put on it - its lifestyle, emotional health and cellular health, working in concert.

Chronic stress shortens telomeres. A sense of purpose quiets the inflammatory response. Happier more resilient humans age better from the inside out.

Anorexia found me at twelve, in 1992 - well described in the textbooks, barely spoken of at the school gates. Prozac, hospital, force-feeding, CBT to the hilt. What reached me was one sentence from an astute psychiatrist: your family has the measles - you just have the spots. I was not broken. I was the visible sign of a system under strain.

So when Imperial published a new psilocybin pilot for anorexia this month, I read it closely - as a doctor, and as someone who once sat on the other side of that table.

The findings are in the carousel. The short version: third independent group to show benefit, longest follow-up yet, a real signal - and fewer than sixty participants across all three trials, with no control group. Convergence is how a signal starts to become a finding. It is still early.

My clinical read: anorexia holds the nervous system in profound threat, and talking therapy asks the thinking brain to override a state it often cannot reach. Psilocybin appears to soften that rigidity long enough for feeling to become possible. The drug opens a door; skilled clinicians hold it open.

For transparency: I know several of these researchers personally and have referred patients into this field. I want this to work - which is exactly why I hold the caveats as firmly as the promise.

A door is opening. What it needs now is larger trials.

*Psilocybin remains a controlled substance in the UK, lawfully available only within approved research. If you are struggling with an eating disorder, is the place to start.

You can do everything “right” - the biomarker panels, the protocols, the supplements - and still not get or feel well.

After 22 years as a medical doctor, and plenty of years as a patient myself, I’ve come to think the reason usually sits upstream of the protocol.

There’s a field for this: psychoneuroimmunology, or PNI. It names something clinicians watch daily and rarely treat directly - the mind, the nervous system and the immune system are in constant conversation. One system, talking to itself.

Near the centre of that conversation sits the HPA axis: the hypothalamic-pituitary-adrenal loop, the brain’s stress-command line. The same hypothalamus and pituitary also head up the thyroid and s*x-hormone axes - which is why stress signalling never stays in its lane. Hold a body in alarm long enough and the ripples reach thyroid, s*x hormones, immunity, sleep, mood. The governor sits in the brain. The effects show up everywhere.

I know this terrain from both sides of the desk: a serious brain injury, Long Covid, real stretches of mental health disturbance, a handful of hormonal diagnoses of my own.

Here’s what that taught me. You can throw supplements and hacks at a dysregulated system indefinitely, and if the terrain isn’t receptive, little of it takes. The container has to be ready to hold the work - and emotional health, with the behaviours wired around it, is often the part quietly deciding whether anything else lands.

One honest caveat: the right tools have their place, and they can open the door. Datis Kharrazian’s *Why Isn’t My Brain Working?* (2013) reframed this for me - that supporting the brain and understanding its chemistry can genuinely change how you feel and function, and in doing so lift someone enough to engage with the deeper work. Motivation and capacity are themselves things you can build.

For the past ten years, I’ve made a quiet ritual of my birthday - not a celebration of me, but an occasion.
A reason to gather brilliant, interesting, integral humans in one room and let the alchemy do its work.

Connection is physiology. When we feel seen, loved and gathered, the nervous system registers safety. Ideas cross-pollinate. Memories are made. Joyspan expands - not as a concept, but as something you can feel in the body on a summer evening surrounded by good people.

Community is one of the most powerful longevity interventions we have. It costs nothing and changes everything.

To everyone who came, contributed, laughed and embodied a little joyspan with me, thank you!
You are the medicine.

I Read “Why Zebras Don’t Get Ulcers” about eight years ago, and the zebra never left me. It flees the lion, the chase ends and it goes back to grazing. The threat passes - and so does the stress.

Most of us aren’t like this. We keep running from lions that aren’t there anymore. The danger has passed - sometimes by years — but the body bypassed the memo. So it keeps reacting to the present through the filter of everything that came before.

“We don’t see things as they are, we see them as we are.” - Anaïs Nin

This is personal. Athlete, childhood trauma, long COVID, immune dysfunction - chronic stress has been written into my own biology. But I also see it every single week in clinic:

The fatigue that sleep doesn’t touch. The insomnia. The anxiety humming under everything. The autoimmune flare tracing back to years of never feeling safe. The binge eating, the scrolling, the second glass, the small addictions we reach for to take the edge off.

Here’s what they all share: we never actually stop. We’re constantly doing, achieving, moving, eating, drinking, obsessing. We never graze.

And that’s where disease comes from - not from stress itself, but from the absence of ease. From never allowing the body to repair, to regenerate, to come down. We’ve optimised ourselves into depletion, mistaking constant motion for progress.

The work isn’t to eliminate stress. It’s to develop the capacity for ease - to learn, again, how to actually rest. To switch off. To let the body do what it was built to do: recover.

Ease - before the disease.

Movement, authentic connection, real rest, a felt sense of safety. Not luxuries. The biology of repair.

If you’ve forgotten how to graze, this one’s for you.

Loved the opportunity to speak at the in London last weekend on my passion topic: emotional health in longevity piece.

This is the bit that gets called soft. It isn’t. It’s upstream of almost everything we measure.

The pressure you don’t switch off from. The grief that never quite landed. The vigilance you’ve carried so long it feels like personality. These run through the same machinery as every metric on your dashboard - HPA axis, autonomic balance, inflammatory signalling, sleep architecture. They show up as the flat HRV, the elevated CRP, the fatigue your bloodwork can’t explain, the sleep that won’t hold.

I work with this from both sides. As a physician trained in psychiatry and performance medicine, and as someone who has lived the biology - eating disorder, traumatic brain injury, Long Covid. That’s why I’m honest with the brilliant, high-performing men and women I see: you don’t need more inputs. You’re already doing enough. What you need is less load on a system that’s been running hot for a long time.

Behaviour change in this group is rarely about discipline. You have plenty. It’s that the body won’t lay down recovery while it’s still bracing. Lighten the load first. Capacity comes back. And with it, the things the metrics were always pointing at anyway - energy, sleep, presence, the ability to actually enjoy the life you’re optimising for.

That is where longevity lives. Not in the avoidance of decline - in the preservation of adaptability. And in joyspan, which I’d argue is the metric we should all be chasing.

International Women’s Day 💜

The world does not need more performative power. It needs more truth, more compassion, and more women standing firmly beside one another.

Today, I’m deeply grateful for the women who support me, and so many others — in medicine and beyond — and who continue to champion women’s health with the nuance, intelligence and humanity it deserves.

To the women who lift me up and see my light: thank you. I hope you know how deeply I see yours too.

I know the central governor well, not just from the science, but from living on the wrong side of its warnings for far too long.

For years I pushed through midlife carrying the perfect storm many women face:

➡️ Hormones shifting
➡️ Young children moving into puberty
➡️ A career that never stopped demanding more
➡️ The invisible emotional labour of holding everyone else up

And like so many women I now support at Wellgevity, I kept going without adequate support, without a “place to fall,” and without giving my brain the signals of safety it needed.

Eventually, the governor did what it’s designed to do:
It slammed the brakes.

Not because I was weak.
Not because I’d “lost drive.”
But because my brain was trying to protect me from the load I refused to acknowledge.

Midlife is an inflection point where biology and life collide. Hormone shifts change how we allocate energy. Parenting teens requires a new bandwidth. Work often peaks just as sleep, recovery and resilience begin to fluctuate.

So many high-performing women suddenly “hit the wall.”
This is not a personal failing - it’s physiology.
A neuroprotective strategy.

If you’re feeling the friction, the slowing, the fatigue… please hear this:

“Slow down before you crash.
Listen before your body forces you to.
Redirect before you have to rebuild from zero.”

Recovery is absolutely possible - but it’s far easier to course - correct than to reverse-engineer after collapse.

Your brain isn’t betraying you.
It’s protecting you with the information it has.

At Wellgevity we help women retrain the governor, rebuild resilience and expand capacity safely - with more energy, not less.

If this resonates, comment “GOVERNOR” below.
You’re not broken - you’re carrying too much on a system designed to protect you.
