Defying death: The origins of ageing

Defying death: The origins of ageing

Author: Financial Times November 26, 2025 Duration: 35:49

How much do we really know about ageing? For decades, scientists have been trying to understand the biology of the ageing process - what happens to our bodies as we get older? And is it possible to slow that process down or even stop it all together?


In this series of Tech Tonic, the FT’s Hannah Kuchler and Michael Peel look into the past, present and future of longevity - the wellness movement focused on extending and bettering your quality of life. Episode 1 follows Hannah as she speaks with UCL professor David Gems about the history of ageing research, and then with longevity researcher Matt Kaeberlein to discuss how the industry has developed - including current drugs that could have anti-ageing effects. Plus, Michael visits the Reviv clinic in London where he experiences, first hand, the growing consumer interest in the longevity craze.

From the Financial Times, FT Tech Tonic steps beyond the breathless headlines and gadget launches to explore how technology is fundamentally reshaping our lives, economies, and social structures. This isn't just a series about the latest app; it's a deep, considered examination of the forces driving the digital age and their often unintended consequences. Each episode grapples with the complex interplay between innovation and its real-world impact, drawing on the FT's global reporting expertise to provide clarity and context. You'll hear conversations that dissect the power dynamics in Silicon Valley, investigate the ethical dilemmas of artificial intelligence, and explore how entrepreneurship is being redefined across different cultures. The podcast digs into the substance behind the hype, asking whether emerging technologies truly deliver on their promise to improve society or if they introduce new perils we are only beginning to understand. By weaving together threads from technology, business, and culture, the discussions offer a nuanced perspective that challenges simplistic narratives. Tune in for thoughtful analysis that connects the dots between boardroom strategies, algorithmic biases, and the everyday experiences that define our increasingly connected world.
