Ageless: Rewriting the Biology of Time

Ageing is not a single clock ticking down. It is a collection of biological processes, habits, signals and adaptations that interact over time. Ageless looks at what ageing actually is, what current biology can and cannot tell us, and where people still have meaningful room to influence the way they age. Martin Rothery separates useful evidence from fashionable claims, explores the relationship between body, behaviour, stress, recovery and expectation, and asks a practical question throughout: what can we sensibly change without pretending time can be defeated? A grounded guide for readers interested in longevity, healthspan and the biology behind growing older.
