One of the characters in this book died of a heart attack, thinking he was dying from a snake bite. Another's heart stopped during a mock execution by bloodletting. The third experienced pain from non-existent defibrillator shocks. What do these cases have in common? Dr. Sandeep Johar, a practicing cardiologist, asked a truly philosophical question about the direct connection between a person’s emotional and physical state. In an effort to unlock the secrets of our most indefatigable organ, he embarked on a historic journey to the birth of heart science. But the answers came when he was able to look at his patients and himself differently. This book will tell you how Roosevelt's death helped doctors advance the study of heart disease; why people in unhappy marriages are more likely to have heart disease than those whose married lives are more joyful, and also what is the fatal mistake of doctors who treat the human heart as a machine.
