How kindness--and other prosocial behaviors toward others--can help us live longer and healthier lives.The science is in: being good is actually good for you. In this bracingly original book, The Biology of Kindness--the first in a trilogy on the topic of daily wellness--the science of mindfulness and the findings of biology come together to show how kindness and optimism improve overall well-being in profound, organic, and demonstrable ways. Daniel Lumera, an expert in meditation and mindfulness, and Immaculata De Vivo, a preeminent researcher in molecular epidemiology, outline a revolutionary approach to health, longevity, and quality of life--and explain the scientific evidence that supports their work.
