"This book details the latest scientific proof that attitudes and emotions do indeed affect physical health and can play a major role in the treatment and prevention of disease. Drawing on landmark studies conducted by distinguished researchers, this book presents a solid foundation of evidence that negative emotions such as worry, anxiety, depression, hostility, and anger can increase susceptibility to disease - and that positive emotions such as optimism, humor, and a fighting spirit can protect health and increase longevity."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
