Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we've come to accept as fact. In Cannibalism: A Perfectly Natural History, zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism's role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona's Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother's skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

    Medical care is in crisis, we are repeatedly told, and so it is. Barely one in five Americans thinks the medical system works well. Enter David M. Cutler, a Harvard economist who served on President Clinton's health care task force and later advised presidential candidate Bill Bradley. One of the nation's leading experts on the subject, Cutler argues in Your Money or Your Life that health care has in fact improvedexponentially over the last fifty years, and that the successes of our system suggest ways in which we might improve care, make the system easier to deal with, and extend coverage to all Americans. Cutler applies an economic analysis to show that our spending on medicine is well worth it--and thatwe could do even better by spending more. Further, millions of people with easily manageable diseases, from hypertension to depression to diabetes, receive either too much or too little care because of inefficiencies in the way we reimburse care, resulting in poor health and in some cases prematuredeath. The key to improving the system, Cutler argues, is to change the way we organize health care. Everyone must be insured for the medical system to perform well, and payments should be based on the quality of services provided not just on the amount of cutting and poking performed. Lively and compelling, Your Money or Your Life offers a realistic yet rigorous economic approach to reforming health care--one that promises to break through the stalemate of failed reform.

    Each person treats his body as an image of society and Mary Douglas examines the varieties of ritual and symbolic expression and the patterns of social ritual in which they are embodied.Natural Symbols is a book about religion, and less directly, about style. It concerns our own society at least as much as any other, and it has stimulated new insights into religious and political movements and has provoked re-appraisals of current progressive orthodoxies in many fields.

    The Haywire Heart is the first book to examine heart conditions in athletes. Intended for anyone who competes in endurance sports like cycling, triathlon, running races of all distances, and cross-country skiing, The Haywire Heart presents the evidence that going too hard or too long can damage your heart forever. You’ll find what to watch out for, what to do about it, and how to protect your heart so you can enjoy the sports you love for years to come. The Haywire Heart shares the developing research into a group of conditions known as “athlete’s heart”, starting with a wide-ranging look at the warning signs, symptoms, and how to recognize your potential risk. Leading cardiac electrophysiologist and masters athlete Dr. John Mandrola explores the prevention and treatment of heart conditions in athletes like arrhythmia, atrial fibrillation and flutter, tachycardia, hypertrophy, and coronary artery disease. He reviews new research about exercise intensity and duration, recovery, inflammation and calcification, and the ways athletes inflict lasting harm. These heart problems are appearing with alarming frequency among masters athletes who are pushing their bodies harder than ever in the hope that exercise will keep them healthy and strong into their senior years. The book is complete with gripping case studies of elite and age-group athletes from journalist Chris Case—like the scary condition that nearly killed cyclist and coauthor Lennard Zinn—and includes a frank discussion of exercise addiction and the mental habits that prevent athletes from seeking medical help when they need it.Dr. Mandrola explains why many doctors misdiagnose heart conditions in athletes and offers an invaluable guide on how to talk with your doctor about your condition and its proven treatments. He covers known heart irritants, training and rest modifications, effective medicines, and safe supplements that can reduce the likelihood of heart damage from exercise. Heart conditions affect hardcore athletes as well as those who take up sports seeking better health and weight loss. The Haywire Heart is a groundbreaking and critically important guide to heart care for athletes. By protecting your heart now and watching for the warning signs, you can avoid crippling heart conditions and continue to exercise and compete for years to come.
