The Disconnection State: Why loneliness is driving biological ageing in ways we are only beginning to measure

The Shape of Medicine: From interruption to trajectory, and the birth of the longevity physician.

A healthy 37-year-old man almost skipped his appointment. What we found changed everything. This episode explores the shift from a world of sudden death to one of slow disease, and why the future of medicine lies not in treating illness after it appears, but in recognising biological change while there is still time to alter the trajectory.

Microplastics, PCOS/PMOS & the Quiet Erosion of Fertility

This episode explores one of the biggest conversations emerging in health right now: microplastics, endocrine disruption and the quiet erosion of fertility. From PCOS (recently renamed PMOS) and hormonal signalling to inflammation, oxidative stress and IVF outcomes, we examine how modern environmental exposures may be influencing reproductive health in ways medicine is only beginning to understand. It’s a conversation about fertility, modern life and the invisible exposures the body is now adapting to every single day. This is a public episode.

Wearables and the Body that Forgot How to Listen

In this episode, I explore what wearables are actually showing us, not just data, but the loss of our ability to feel ourselves clearly. From heart rate variability to sleep and glucose, these devices are not creating new information. They are restoring access to signals we’ve become disconnected from. I walk through the physiology behind what your wearable is measuring, why behaviour changes when biology becomes visible, and where these tools can both help and harm. This is not about optimisation. It is about awareness, pattern recognition, and intervening earlier, while the body is still adaptable. The question is not which wearable to buy.It is what has changed in your life that you need one to see what your body is already trying to tell you. This is a public episode.

The Disconnection State: Why loneliness is driving biological ageing in ways we are only beginning to measure

In this episode, we examine loneliness as a chronic biological stressor. Associated with a mortality risk similar to smoking 15 cigarettes a day, it can accelerate biological ageing by around four years. We unpack how this shapes the nervous system, immunity, and aging itself. This is a public episode.

The Peptide Age

Peptides are everywhere right now. Promising faster recovery, better sleep, and improved muscle repair. But what do they actually do and why do so many people feel like they need them? This episode breaks down the science, the hype, and what the peptide trend reveals about modern biology. This is a public episode.
