We have a lifetime’s association with our bodies, but for many of us they remain uncharted territory. The doctor takes us on a journey through health and illness, offering insights on everything from the ribbed surface of the brain to the secret workings of the heart and the womb; from the pulse of life at the wrist to the unique engineering of the foot. If the body is a foreign country, then to practise medicine is to explore new territory: the explorer and author of Empire Antarctica leads the reader on an adventure through what it means to be human.
