'Classic, wry, gleeful Bryson... richly interesting... an entertaining and absolutely fact-rammed book. If it sells hundreds of thousands of copies, like the last one, it will be no bad thing.' * Sunday Times * A directory of wonders. Extraordinary stories about the heart, lungs, genitals ... plus some anger and life advice - all delivered in the inimitable Bryson style -- Gavin Francis * Guardian * SCIENCE BOOK OF THE YEAR 2019: 'so packed with arresting facts (you eat 60 tons of food in a lifetime) and unlikely anecdotes (such as Isambard Kingdom Brunel's six weeks with a half-sovereign lodged in his throat) that you barely notice the sheer volume of anatomical knowledge you're digesting ... makes complex subjects simple and eminently entertaining.' * The Sunday Times * Bryson feeds the pith, pulp and bitter pips of a subject into his brain and produces a sweet, zingy quantity of juice - this book is a delight. * The Spectator * Remarkable ... Every page is dense with scientific facts written as vividly as a thriller, as well as answers to conundrums such as why we don't fall out of bed when we are asleep ... It is woven through with the kind of human stories that Bryson has made his trademark. * Mail on Sunday *
