FT Tech Tonic19 Nov 2025

Coming soon: Defying death

Investors are spending billions of dollars on novel ways to extend human life through inventive treatments, therapies, and even manipulating our genes. And increasingly, it seems as though anti-ageing efforts have moved from the super rich to a mass market consumer industry. In this series, we’re covering the past, present and future of the longevity movement. We’ll be looking at where the fixation on longevity is coming from, and trying to understand the practical and ethical issues at the heart of this cutting-edge field of research.

From Silicon Valley fantasies, to Singaporean health spas, to Colombian genetic clinics and beyond, the FT’s Hannah Kuchler and Michael Peel ask whether breakthroughs in science and technology can really help us live longer, and even stop us aging altogether.
