The surprising and important story of how humans gained what amounts to an extra life, from the bestselling author of How We Got to Now and Where Good Ideas Come FromAs a species we have doubled our life expectancy in just one hundred years. 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?
A study in how meaningful change happens in society, Unexpected Life is an ode to the enduring power of common goals and public resources. The most fundamental progress we have experienced over the past few centuries has not come from big corporations or start-ups. It has come, instead, from activists struggling for reform; from university-based and publicly funded scientists sharing their findings open-source-style; and from nonprofit agencies spreading new innovations around the world.

1The Long Ceiling
Measuring Life Expectancy
In the spring of 1967, a sociology graduate student from Harvard named Nancy Howell took a flight from Boston to Rome with her new husband, an anthropologist named Richard Lee. After a few days in Italy, they flew to Nairobi, where they met an academic friend of Richard's and visited the Hadza tribes living in the region. From there they flew to Johannesburg,where they loaded up on supplies and socialized with a few more researchers in the area. They purchased a truck and drove north to the newly independent country of Botswana, picking up supplies in its new capital, then traveling northwest toward the swampy oasis of the Okavango Delta, recently flooded by seasonal rains. They rented a postbox in the town of Maun, the last outpost that would contain modern amenities like convenience stores and petrol stations. From Maun, they drove about 150 miles west, on unpaved roads, to the small village of Nokaneng, on the western periphery of the Kalahari Desert.
By this point in their journey, it was July in the Southern Hemisphere, but the winter precipitation that had flooded the Okavango Delta was nowhere in sight at the edge of the Kalahari. The newlyweds created a staging ground in Nokaneng, leaving behind sufficient petrol for future travels, and then set out due west across the desert, toward the Namibian border. In the end, it took them eight hours to drive sixty miles through arid terrain.
It was a grueling voyage, and in a sense, it was also a journey back in time. At the end of their eight-hour pilgrimage lay one of few regions of the Kalahari with sufficient water to support small communities of human beings, thanks to the nine waterholes spread out across an otherwise barren, flat landscape roughly 100,000 square miles in size. This more hospitable stretch of the Kalahari was sometimes referred

to as the Dobe region, after the name of one of its waterholes. Howell and Lee had made their arduous journey because the Dobe region was the home of the Kung people, a hunter-gatherer society that had been almost miraculously isolated from all the conventions and technology of modern life. The Kung had managed to survive the preceding bloody centuries with almost no contact with other African societies and their European colonizers. They were protected, as Howell would later observe, "by the simple fact that none of the stronger peoples of southern Africa wanted to take their territory away from them, or even share it."
Like many surviving hunter-gatherer societies around the world, the Kung people offered Western anthropologists a provocative hint of the ancestral environment that had shaped most of the evolutionary history of Homo sapiens, before the agricultural revolution first arrived roughly ten thousand years ago. Lee had already visited the Kung society several times before 1967 to study their social organization, their food production techniques, and their strategies for managing and sharing resources within the community. Lee's research had been instrumental in proposing a new way of thinking about hunter-gatherer communities, one that undermined the long-standing view, most famously captured in Thomas Hobbes's description of the "state of nature" as "solitary, poor, nasty, brutish and short." Observed up close, the Kung did not appear to be struggling to get by, as Hobbes had assumed, in an arduous existence on the edge of starvation. Despite the paucity of natural resources around them, they seemed instead to enjoy a remarkably high standard of living, working less than twenty hours a week to support their nutritional needs. Based on similar research conducted on hunter-gatherer cultures in the Pacific, the anthropologist Marshall Sahlins had recently proposed a term for this reimagined model of early human social organization: the "original affluent society."
