An infectious laugh!
The Washington Post reports that scientists have found that happiness is contagious and can spread like a virus. The study was conducted over 20 years on more than 4,700 people and demonstrates that people who are happy or become happy boost the chances that someone they know will be happy.
In HOW HAPPY CAN YOU BE?, filmmaker Line Hatland, who admits to not being as happy as she'd like to be, seeks answers to this question by interviewing and showing the work of some of the world's leading researchers on happiness, or "objective well being," including psychologists, anthropologists, sociologists, and neuroscientists.Labels: happiness, medecine, science, sociology, study
