We hear the story of Mary Gillespie, a woman born with normal hearing and vision, but who developed several illnesses starting at age ten. Gradually, she became deaf-blind. Now living in Los Angeles, Mary is a regular volunteer at the Braille Institute, where we recorded this remarkable episode of Humankind.
