Re:Age

Bryan Johnson built his life around the belief that biological decline could be negotiated with. Measured, tracked, interrogated and adjusted, every part of the body became something to watch more closely. He did not merely become interested in health. He turned his body into a living experiment in control. And then came the sentence that made the whole project feel suddenly more human. “My stomac...

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. This is a public episode. If you would like to discuss th...

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...

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...

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. If you would like to discuss this with other subscribers or get access to bonus episodes, visit...

This episode breaks down the science, the hype, and what the peptide trend reveals about modern biology. This is a public episode.
