Despite what you may have been told, we are not inherently selfish. The truth is that we are naturally kind. Scientific evidence has shown that kindness changes the brain, affects the heart and immune system, serves as a remedy for depression, and even slows down the aging process. In fact, we are genetically programmed to be kind. In "The Five Side Effects of Kindness," David Hamilton demonstrates that the effects of kindness are felt daily in our nervous system. When we are kind, we feel happier and our bodies are at their healthiest. In his down-to-earth and accessible style, David shares how kindness makes us happier, is good for the heart, slows aging, improves relationships, and is contagious.
