Dr. John Cacioppo

Today, Dr. John Cacioppo, the Tiffany and Margaret Blake Distinguished Service Professor and Director of the Center for Cognitive and Social Neuroscience at the University of Chicago, and I discuss his new book, LONELINESS, which is based on over 30 years of scientific study. Did you know that loneliness is as large a risk factor for major diseases as obesity, smoking and substance abuse? Did you know that over 20% of American adults suffer needlessly from severe loneliness and social isolation? Did you know that banishment was the most serious punishment meted out in the ancient days--and even now? Do you know that loneliness can be relieved?
