The pursuit of pleasure is a central drive of the human animal. Evolution has, in effect, hardwired us to catch a pleasure buzz from a wide variety of experiences from crack to cannabis, from medication to masturbation, from Bordeaux to beef. Professor of neuroscience at The Johns Hopkins University School of Medicine David Linden joins us in studio to talk about how understanding the biological basis of pleasure leads us to fundamentally rethink the moral and legal aspects of addiction to drugs, food, sex, and gambling and how industries manipulate these pleasures in the marketplace.
