What is the neurological difference between happiness and pleasure? Has society's exploitation of pleasure systematically weakened our grasp on happiness? What has caused the twin epidemics of these healthy emotions' negative extremes: addiction (from too much pleasure) and depression (from too little happiness)?Dr. Robert Lustig, Emeritus Professor at the University of California, answered these questions at San Francisco's BookShop West Portal in November 2017.This is a passionate, information-packed, eye-opening summary of Dr. Lustig's latest book "The Hacking of the American Mind."Produced for Wonderfest, the Bay Area Beacon of Science, by videographer Eric Yao.
