Longtime NPR host Diane Rehm has released a new documentary, 'When My Time Comes,' about the nationwide push to legalize medical aid in dying — an advocacy journey she began after watching her husband decide to die by forgoing food and water after his Parkinson's disease became unbearable. She joined Jim Braude, along with a local advocate featured in the film, retired internist Dr. Roger Kligler, who is terminally ill with cancer.
