Cognitive psychologist and neuroscientist Daniel J. Levitin has spent almost three decades studying the power of the human brain — from how memory works to how we can make good decisions in an age of information overload. In his most recent book, Successful Aging, he discusses strategies for maintaining mental vitality in our old age. They include taking walks, getting better sleep, and trying new things. They don’t include constantly checking e-mail, Twitter, and Facebook, which he describes as a “neural addiction.”
