Debbie Melman: Dr. Grandin's latest book is visual thinking, the hidden gifts of people who think in pictures, patterns and abstractions. In a 2010 Ted talk she said that if by some magic autism had been eradicated from the face of the earth, men would still be socializing in front of a wood fire at the entrance to a cave. She says her happiest times are doing interesting things that improves treatment of animals. Debbie Melman: Thank you for joining us today on Design Matters.
