Can a tumor ever be a source of good? Neurologist Dr. Orrin Devinsky thinks so. He recalls the true story of a man, his tumor, and a euphoric reaction to safety pins. Next, Mark Salzman reads from his novel Lying Awake. When a nun develops a brain tumor, she finds the spiritual communion with God she's been seeking. But what will happen when she’s forced to choose between physical health and religious enlightenment? It turns out Dr. Devinsky sees many real patients like this fictional nun, patients who miss their deadly tumors once they're gone.
