Sheryl Sandberg on grief, silence and ‘Option B’

As one of the best known female executives in the world, Sheryl Sandberg had resources and support when her husband died at 47, but that didn't stop grief from engulfing her and their children. In her new book "Option B," Sandberg writes about grief and resilience in the face of adversity, and offers advice for others experiencing personal tragedy. Sandberg sits down with Judy Woodruff.
