What Doesn't Kill Us

A New York Times bestseller and a Book of the Year for the Evening Standard and The Times . Is getting a little less comfortable the key to living a happier, healthier life? When journalist Scott Carney came across a picture of a man in his fifties sitting on a glacier in just his underwear, he assumed it must be a hoax. Dutch guru Wim Hof claimed he could control his body temperature using his mind and teach others to do the same. Sceptical, Carney signed up to Hof’s one-week course, not realising that it would be the start of a four-year journey to unlock his own evolutionary potential. From hyperventilating in a Polish farmhouse to underwater weight training in California, and eventually climbing Mt Kilimanjaro wearing just shorts and running shoes, Carney travelled the world testing out unorthodox methods of body transformation and discovering the science behind them. In What Doesn’t Kill Us he explains how getting a little less comfortable can help us to unlock our lost evolutionary strength.

What Doesn't Kill Us, a New York Times bestseller, traces our evolutionary journey back to a time when survival depended on how well we adapted to the environment around us. Our ancestors crossed deserts, mountains, and oceans without even a whisper of what anyone today might consider modern technology. Those feats of endurance now seem impossible in an age where we take comfort for granted. But what if we could regain some of our lost evolutionary strength by simulating the environmental conditions of our ancestors? Investigative journalist and anthropologist Scott Carney takes up the challenge to find out: Can we hack our bodies and use the environment to stimulate our inner biology? Helping him in his search for the answers is Dutch fitness guru Wim Hof, whose ability to control his body temperature in extreme cold has sparked a whirlwind of scientific study. Carney also enlists input from an Army scientist, a world-famous surfer, the founders of an obstacle course race movement, and ordinary people who have documented how they have cured autoimmune diseases, lost weight, and reversed diabetes. In the process, he chronicles his own transformational journey as he pushes his body and mind to the edge of endurance, a quest that culminates in a record-bending, 28-hour climb to the snowy peak of Mt. Kilimanjaro wearing nothing but a pair of running shorts and sneakers. An ambitious blend of investigative reporting and participatory journalism, What Doesn't Kill Us explores the true connection between the mind and the body and reveals the science that allows us to push past our perceived limitations.
