The hidden power of smiling

Ron Gutman is the founder and CEO of HealthTap, a personalized health-info site and in this TED's video he reviews a raft of studies about smiling. Did you know your smile can be a predictor of how long you'll live and that a simple smile has a measurable effect on your overall well-being? Well, as far as I am concerned, smile and smiling is written deep down in my DNA, it's "hard coded" into my personality: I can't be really myself without smiling. Please, keep smiling and try to "contaminate" as many people as possible. :-)
