In this fascinating journey through the human body and across the globe, Dr Reisman weaves together stories about our insides with a unique perspective on life, culture, and the natural world. In his beautifully written prose, Dr Jonathan Reisman - physician, adventure traveller and naturalist - allows readers to navigate their insides like an explorer discovering a new world. Through his offbeat adventures in healthcare and travel, Reisman discovers new perspectives on the body: a trip to the Alaskan Arctic reveals that fat is not the enemy, but the hero; a stint in the Himalayas uncovers the boundary where the brain ends and the mind begins; and eating a sheep´s head in Iceland offers a lesson in empathy. By relating his experiences in far-flung lands and among unique cultures back to the body´s inner workings, he shows how our organs live inextricably intertwined lives in an internal ecosystem that reflects the natural world around us. Reisman´s unique perspective on the natural world and his expert wielding of wit ultimately helps us make sense of our lives, our bodies and our world in a way readers have never before imagined. ´An elegant, elegiac, and deeply enjoyable meander through human anatomy . . . the images Reisman conjures will linger long after you´ve devoured his delightful prose.´ - Nicola Twilley, co-author of Until Proven Safe and co-host of Gastropod podcast
