Often we think of life and death as opposite sides of a coin — categories as final as they are discrete. But in an age when machines can keep hearts pumping and lungs breathing, the line between life and death can sometimes start to blur. Modern medicine pushes us to think differently, ask if perhaps life and death are instead two points on a spectrum of existence. In this episode, The Pulse explores the space between those points. How do we define life and death — medically and culturally? We hear about a court case challenging the legal definition of death; the evolving debate over end-of-life care; and what scientists are saying about near-death experiences.
