When I first started the Harvard course about happiness, I had several questions that I hoped to have answered. After six weeks of reading articles, watching videos and contributing to class discussion boards, I've officially completed Harvard University's " Managing Happiness " course, led by social scientist and Harvard professor Arthur Brooks . Guillaume Duchenne de Boulogne, a French neurologist who studied facial expressions, was particularly interested in what some call the "Duchenne smile," a smile that engages the muscles around your mouth and eyes. "If we force a Duchenne smile, we start to feel happier," Brooks says in one of the course's videos. The Duchenne smile teaches us that "you can stimulate your happiness and improve it," sometimes by just genuinely smiling, Brooks adds.
