Defying death: The origins of ageing

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.
