Why Our Obsession With Living Longer Has Gone Too Far

Oct 14, 2026 · 14m

Summary

Seamus O'Mahony discusses his new book, The Longevity Delusion, arguing that the modern obsession with supplements and novel interventions is largely driven by commercial interests and bad science. He contends that the primary determinants of longevity are social factors like income and education, rather than individual behaviors or pharmaceuticals. The conversation highlights the significant gap between lifespan and healthspan, particularly in the UK and US, and warns against the risks of unregulated substances and the "magic pill" mentality.
