This week, Washington, D.C. is hosting two meetings focused on health: TEDMED, of course, is underway, as well as the 2012 National Health Promotion Summit — which is where our team is based. We continue live tweeting, and our tweets can be spotted in the tweet stream in the right margin of this webpage. But if you can’t be at this prevention-focused meeting in person, you can follow all of the chatter on Twitter with hash tag #HealthSummit. Interested in what folks are saying about TEDMED? Follow via #TEDMED. Join the conversation.
