Doctors’ Notes: Healthy Longevity Special at Hay Festival
16/06/2026 | 48 mins.
This extended episode of What's Up Docs? features Chris and Xand van Tulleken's full live conversation with Professor Devi Sridhar at Hay Festival.
Going deeper than the main episode, they explore the tension between individual responsibility and structural change, and why asking "how do I stay healthy?" might be the wrong question altogether. Devi draws on her work across governments and health systems worldwide to examine what genuinely moves the needle on population health. Chris and Xand also ask how Devi's work shapes the way she lives, and what single policy change she'd make tomorrow if she could.

How to Live Healthier for Longer
16/06/2026 | 28 mins.
Welcome to What's Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore the ideas shaping our health and wellbeing.
In this episode, recorded live at Hay Festival, they're joined by Professor Devi Sridhar, Chair of Global Public Health at the University of Edinburgh, to ask how we can live longer, healthier lives.
They dig into the difference between life expectancy and healthy life expectancy, and why the latter is falling in places like the UK. Devi unpacks the biggest factors that shape how well we age, from diet and exercise to mental health and the environments we live in, and shares what decades of working across countries and health systems has taught her.
They challenge the idea that health is simply a matter of individual choice, exploring how the society you're born into can shape your chances of a long and healthy life more than any supplement or wellness hack.

Doctors' Notes: Male Contraception
02/06/2026 | 17 mins.
Chris and Xand van Tulleken take a deeper dive into male contraception with Professor Richard Anderson.
They explore why, despite decades of research, new male contraceptive options are still limited. From funding gaps to shifting attitudes, they unpack the social and scientific barriers that have shaped progress so far.
They also look at how people feel about the idea of male contraception, whether those attitudes are changing, and what it could mean for relationships if new options become available.
Along the way, they tackle common misconceptions and consider what the future of shared contraceptive responsibility might look like.
