Many people remember the beaming face of Christiaan Barnard, the South African surgeon, after he performed the first human heart transplant, and captured the world's imagination. It was a stunning achievement, but he was not alone. In truth it was a four-way race, a fierce struggle fraught with passionate rivalry. The other three surgeons-Adrian Kantrowitz, Norman Shumway, and Richard Lower-were giants in the field, and by early December 1967 they and Barnard were each poised to snatch the victor's laurels. Each had spent years perfecting techniques that would lead to a successful heart transplant; each had monitored his chosen patient's condition, watching the clock, hoping a donor would be found in time. Some of these men were friends; others were enemies. Only one of them would be the first. From a dank, underequipped hospital in Cape Town to a cramped lab in San Francisco, the surgeons worked their own individual miracles to prolong their patients' lives, testing the limits of science, and nature itself. Like the classics of medical adventure-from James Watson's The Double Helix to John Barry's The Great Influenza-Every Second Counts is an unforgettable story of not only competition and fame, but of life and death.

    All the advances of modern life--the medical breakthroughs, the public health institutions, the rising standards of living--have given us each about twenty thousand extra days on average. There are few measures of human progress more astonishing than our increased longevity.This book is Steven Johnson's attempt to understand where that progress came from. How many of those extra twenty thousand days came from vaccines, or the decrease in famines, or seatbelts? What are the forces that now keep us alive longer? Behind each breakthrough lies an inspiring story of cooperative innovation, of brilliant thinkers bolstered by strong systems of public support and collaborative networks.But it is not enough simply to remind ourselves that progress is possible. How do we avoid decreases in life expectancy as our public health systems face unprecedented challenges? What current technologies or interventions that could reduce the impact of future crises are we somehow ignoring?
