Can You Do Too Much for Your Health? Biological Age, NAD+ and Longevity Hype

Longevity medicine has created a strange new kind of patient: the healthy person convinced something must be wrong.

A wearable flags poor recovery. One test says your body is ageing faster than it should. Another gives you a completely different answer. And suddenly, someone who felt perfectly well starts wondering what needs fixing.

In this episode, host Daphna Stern sits down with Dr Chris Bachtsetzis, a physician practising general, preventive and longevity medicine in Switzerland.

Dr Chris sees patients across the full spectrum. Some have virtually unlimited budgets and are prepared to spend heavily on their health, travelling between clinics and trying the latest tests and treatments. Others simply want to stay healthy for as long as possible. And when it comes to those with money to spend, Dr Chris is often the person telling them to do less.

The conversation gets into where more testing becomes more noise, why Dr Chris questions the precision of biological age testing, and why he believes the enthusiasm around NAD+ has moved faster than the evidence. Daphna also challenges him on a more fundamental question: what does a longevity doctor actually offer that a very good GP should not already be doing?

They also explore what happens when the pursuit of better health goes too far. Can constantly tracking biomarkers and wearable scores turn a healthy person into an anxious patient? And if money really is no object, should you actually be doing more?

This is a conversation about how far to go in the pursuit of better health, and why knowing when to stop can matter as much as knowing what to do.
