Dr. Louis Francescutti on how our brains have not evolved enough for modern times

Our human hardwiring has not kept pace with social change, according to a new book co-authored by Edmonton's Dr. Louis Francescutti. The emergency physician outlines how our historic drive for survival clashes with the dominance of social media, and how hospitals can be danger zones as he talks to Global News about "Hardwired: How Our Instincts to Be Healthy are Making Us Sick."
