INSIDER ADVICE FOR STUDENTS FROM STUDENTS

The New York Times bestselling author of Better and Complications reveals the surprising power of the ordinary checklist

We live in a world of great and increasing complexity, where even the most expert professionals struggle to master the tasks they face. Longer training, ever more advanced technologies—neither seems to prevent grievous errors. But in a hopeful turn, acclaimed surgeon and writer Atul Gawande finds a remedy in the humblest and simplest of techniques: the checklist. First introduced decades ago by the U.S. Air Force, checklists have enabled pilots to fly aircraft of mind-boggling sophistication. Now innovative checklists are being adopted in hospitals around the world, helping doctors and nurses respond to everything from flu epidemics to avalanches. Even in the immensely complex world of surgery, a simple ninety-second variant has cut the rate of fatalities by more than a third.

In riveting stories, Gawande takes us from Austria, where an emergency checklist saved a drowning victim who had spent half an hour underwater, to Michigan, where a cleanliness checklist in intensive care units virtually eliminated a type of deadly hospital infection. He explains how checklists actually work to prompt striking and immediate improvements. And he follows the checklist revolution into fields well beyond medicine, from disaster response to investment banking, skyscraper construction, and businesses of all kinds.

An intellectual adventure in which lives are lost and saved and one simple idea makes a tremendous difference, The Checklist Manifesto is essential reading for anyone working to get things right.

How much do parents really matter?

These may not sound like typical questions for an economist to ask. But Steven D. Levitt is not a typical economist. He studies the riddles of everyday life—from cheating and crime to parenting and sports—and reaches conclusions that turn conventional wisdom on its head. Freakonomics is a groundbreaking collaboration between Levitt and Stephen J. Dubner, an award-winning author and journalist. They set out to explore the inner workings of a crack gang, the truth about real estate agents, the secrets of the Ku Klux Klan, and much more. Through forceful storytelling and wry insight, they show that economics is, at root, the study of incentives—how people get what they want or need, especially when other people want or need the same thing.

Michael Roizen and Mehmet Oz, America's most trusted doctor team and authors of the bestselling YOU series, are now translating this cutting-edge information to help you shave inches off your waist. They're going to do it by giving you the best weapon against fat: knowledge. By understanding how your body's fat-storing and fat-burning systems work, you're going to learn how to crack the code on true and lifelong waist management.

Roizen and Oz will invigorate you with equal parts information, motivation, and change-your-life action to show you how your brain, stomach, hormones, muscles, heart, genetics, and stress levels all interact biologically to determine if your body is the size of a baseball bat or of a baseball stadium. In YOU: On a Diet, Roizen and Oz will redefine what a healthy figure is, then take you through an under-theskin tour of the organs that influence your body's size and its health. You'll even be convinced that the key number to fixate on is not your weight, but your waist size, which best indicates the medical risks of storing too much fat.

Because the world has almost as many diet plans as it has e-mail spammers, you'd think that just about all of us would know everything there is to know about dieting, about fat, and about the reasons why our bellies have grown so large. YOU: On a Diet is much more than a diet plan or a series of instructions and guidelines or a faddish berries-only eating plan. It's a complete manual for waist management. It will show you how to achieve and maintain an ideal and healthy body size by providing a lexicon according to which any weight-loss system can be explained. YOU: On a Diet will serve as the operating system that facilitates future evolution in our dieting software. After you learn about the biology of your body and the biology and psychology of fat, you'll be given the YOU Diet and YOU Workout. Both are easy to learn, follow, and maintain. Following a two-week rebooting program will help you lose up to two inches from your waist right from the start.

With Roizen and Oz's signature accessibility, wit, and humor, YOU: On a Diet -- The Owner's Manual for Waist Management will revolutionize the way you think about yourself and the food you consume, so that you'll diet smart, not hard. Welcome to your body on a diet.
