Dr. Francis Collins has been at the forefront of the world's most advanced biomedical research. He led the Human Genome Project and was the longest-serving director of the National Institutes of Health. He is drawing on his career to focus on what he sees as the core pillars of wisdom during a time of deep polarization. Geoff Bennett sat down with Collins to discuss his book, "The Road to Wisdom."
