'It would be hard to find anyone better qualified to write a book on the limits of human physiology than Dr Kevin Fong. His experiences in human spaceflight at NASA, in frontline medicine, and his deep scientific knowledge, shine through. If you want to know what the human body can take, and why we must continue to push ourselves beyond the limit in the name of exploration, then read this book.'
'I was hooked. The book could easily have ended up as a series of Boy's Own tales of derring-do, but Fong elegantly balances heroism with rationalism, courage with compassion, shock with humility and humour.'
'If you have a sense of adventure and the miracle of life within you, then this book is for you... [Kevin Fong is] Brian Cox with a stethoscope.'
'It's terrifying but fascinating stuff... a gripping read.'
'Fong has come up with an often fascinating and actually rather inspiring account of western medicine's ever-increasing expertise.'
'You don't have to have a degree in astrophysics or medicine to enjoy this book, just an interest in humanity and the human body. Since we all have one, that would be just about everyone.'
'His background makes him particularly well suited to writing a book about the limits of the human body, which he does with considerable skill and detail... This is an excellent book that makes you appreciate our species' remarkable resilience.
