What happens to your body when you take risks? What happens to it when you make or lose a lot of money? In this starling book, physiologist and former Wall Street trader John Coates vividly illustrates what happens to your body when you engage in risk taking. Your transform into a different person, a change Coates refers to as 'the hour between dog and wolf.' He tells a gripping story of a group of traders caught in a bull market and then a crash. As the excitement builds he takes us inside the traders' bodies to see the biology of risk taking at work, a biology shared by athletes, politicians, soldiers-anyone who ventures beyond their safety zone. Coates also discusses how men and women excel at different types of risk; how the stress of failure damages our health; and how we can train our bodies so that they help rather than hinder our risk taking. Revealing the biology behind bubbles and crashes, The Hour Between Dog and Wolf shed new and surprising light on issues that affect us all. 'Brilliant . . . Coates has a gift for vivid description, as the sights, sounds, and (unfortunately) smells of the bank come to life in this prose . . . This book should be top of the summer reading list.' Financial Times 'A fascinating examination of how humans think not just with the brain but also the body during periods of acute stress. It is a must-read.' Soldier
