What happens to us when we die? Where does the line between life and death really or finally reside? These questions are as old as human consciousness itself. On this encore presentation of ST, we present an interesting discussion with Dr. Sam Parnia, the director of the well-known AWARE Study (as in, "AWAreness during REsuscitation") and one of the world's leading experts on the scientific study of death and near-death experiences. Dr. Parnia joins us to talk about his new book, "Erasing Death: The Science That Is Rewriting the Boundaries Between Life and Death." He says that death does not actually occur at a precise moment in time. Rather, it is a process --- and one that can be interrupted well after it has begun. This has led to advancements at the vanguard of critical care and resuscitation medicine that might someday give us science-based answers to humanity's ultimate mystery: What happens to us during and after death?
