Columbia University doctor Kelli Harding never intended to explore the invisible factors behind our health. But then there were the rabbits. In 1978 a seemingly straightforward study designed to establish the relationship between high cholesterol and heart health in rabbits discovered that kindness - in the form of a particularly nurturing researcher - made the difference between a heart attack and a healthy heart. As Dr Harding reveals in this eye-opening book, the rabbits were just the beginning of a much larger story. What truly makes us sick - and what can make us healthy? Groundbreaking research shows that love, friendship, community, life's purpose, our environment, and kindness can have a far greater impact on our health than anything that happens in the doctor's office. With engaging stories and compelling evidence, Dr Harding gives you a new model to take charge of your health and happiness.
