They evaded predators and built civilizations with just their raw brainpower and inner grit. But things have changed and now comfort is king. Today we live in the thrall of constant climate control and exercise only when our office schedules permit. The technologies that we use to make us comfortable are so all encompassing that they sever the biological link to a changing environment. Now we hate the cold and the heat. We suffer from autoimmune diseases. And many of us are chronically overweight. Most of us don't even realize that natural variation - sweating and shivering - is actually good for us. The new book  uncovers how just about anyone can reclaim a measure of our species' evolutionary strength by tapping into the things that feel uncomfortable.

They are connecting with their environment and, whether they realize it or not, are changing their bodies. Perhaps no one exemplifies this better than , whose remarkable ability to control his body temperature in extreme cold has sparked a whirlwind of scientific study. Because of him, scientists in the United States and Europe are just beginning to understand how cold adaptation might help combat autoimmune diseases and chronic pains and, in some cases, even reverse diabetes.
