Biochemist Gregory Petsko makes a convincing argument that, in the next 50 years, we’ll see an epidemic of neurological diseases, such as Alzheimer’s, as the world population ages. His solution: more research into the brain and its functions. He also shares a few simple things we can do for ourselves to keep our brains healthy. (Recorded February 2008 in Monterey, California. Duration: 3:46.)
