FROM THIS EPISODE
Photographer Joel Meyerwitz goes on a roadtrip with his father, who suffers from Alzheimer's. A funny, poignant story. Also, a blind man named Walt Strummer who has asked disabled people about their dreams - in their dreams, the blind see, and people in wheelchairs walk. Mr Strummer says it took two decades of blindness before he showed up blind in his own dreams. And other stories.
