Humans have become much taller and heavier, and experience healthier and longer lives than ever before in human history. However it is only recently that historians, economists, human biologists and demographers have linked the changing size, shape and capability of the human body to economic and demographic change. This fascinating and groundbreaking book presents an accessible introduction to the field of anthropometric history, surveying the causes and consequences of changes in health and mortality, diet and the disease environment in Europe and the United States since 1700. It examines how we define and measure health and nutrition as well as key issues such as whether increased longevity contributes to greater productivity or, instead, imposes burdens on society through the higher costs of healthcare and pensions. The result is a major contribution to economic and social history with important implications for today's developing world and the health trends of the future.

A new collection of stories from the Pushcart Prize-winning author of The Mysterious Secret of the Valuable Treasure. Glittering with mischief and perversity, Jack Pendarvis’s latest collection of short fiction introduces readers to a world of losers poised on the brink of all sorts of disaster – a world only a wink and a nod away from our own. In the title novella a fundamentalist teenager must single-handedly confront the horrors of a spiritual quest filled with secular humanists, an apocalyptic folk artist, and a couple of movie stars. The other stories deal poignantly with – among other things – a young millionaire pretending to be a detective, Alabamians getting violent in a New York bar, the good folks who invented diarrhea-inducing chewing gum, a man who becomes an impromptu drug mule, magnetic healers, and a candidate making a sad speech for office. Underlying each comedic gem and neurotic twist is an intelligence and empathy rarely found in modern satire. Like the best guidebooks, Your Body is Changing will invite you in with its zany humor and indict you with its moving truths.

A biology professor’s illuminating tour of the physical imperfections—from faulty knees to junk DNA—that make us human. ¶“A funny, fascinating catalog of our collective shortcomings that’s tough to put down.”—Discover ¶ We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution’s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there’s been some kind of mistake? As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is indeed nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them. A rollicking, deeply informative tour of humans’ four-billion-year-and-counting evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.
