What Doesn't Kill Us: how freezing water, extreme altitude, and environmental conditioning will renew our lost evolutionary strength

What are our bodies really capable of?


We like to sit in air-conditioned comfort, yet each year millions of
ordinary people train in CrossFit boxes, compete in Tough Mudders, and
challenge themselves in Spartan races. They are connecting with their
environment and, whether they realise it or not, unlocking their hidden
evolutionary potential.


No one exemplifies this better than Wim Hof, whose remarkable ability
to control his body temperature in extreme cold has sparked a whirlwind
of scientific study. Through him, we are just beginning to understand
how cold adaptation might combat autoimmune diseases and chronic pain -
and possibly even reverse the development of one of our greatest
killers: diabetes.


Award-winning journalist Scott Carney investigates the astonishing
and sometimes dangerous world of body transformation. He reveals
techniques you can try at home, but his own journey culminates in a
record-bending, 28-hour climb to the snowy peak of Mt Kilimanjaro -
