Ambitious and energetic . . . Give[s] a startling round-up of the biological factors that make us age and the emerging techniques to tackle them . . . Writing with the vim of a Bill Bryson and the technical knowledge of a scientist, Steele gives us a chance to grasp what's at stake in this dazzling, daunting age where big data meets human biology ― Independent

What if we had a cure for getting old? A bold young scientist argues that medicine and technology will stop bodily decay . . . Fascinating ― The Times

Ageless employs a scientific vocabulary - autophagy, amyloids, adducts and countless other specialised terms abound. But the book is nevertheless accessible, its style chatty and engaging . . . This is an enthralling book . . . Ageless is a rich and exciting exploration of that surprisingly intriguing topic we'd rather not talk about: old age ― Irish Times

A fascinating read with almost every page bursting with extraordinary facts . . . Steele is not a crank or a snake-oil salesman. He's not a 'wellness' YouTuber. He doesn't work for Goop. He's a biologist . . . We can take what he says seriously ― Mail on Sunday

There are some incredible revelations in this book. The science is fascinating . . . What Steele says is both revolutionary and important - life-changing in the true sense of the word. His thinking is bold, visionary, utopian ― The Herald

A fascinating book delivering an education into the ageing process and an insight into the possibilities of the future -- Tim Lovejoy

Ageless is an outstanding, totally accessible exposition of why ageing can and should be understood as a medical problem, and of how the world's leading medical researchers are solving it. An absolute tour de force, it will surely save many lives by inspiring new recruits to join this crusade -- Aubrey de Grey, Chief Science Officer, SENS Research Foundation

An immensely important book. Steele surveys the biology of human ageing, as well as the cutting-edge research on how to prevent it. The first person to achieve immortality may already have been born. Is it you?! -- Professor Lewis Dartnell, author of 'Origins'

This is an essential book for anyone interested in the fast-developing science of longevity -- Jim Mellon, Chairman of Juvenescence

What if we could slow down the process of ageing - or even stop it?
