A conversation with Temple Grandin. She is a university professor, a diagnosed autistic, and has designed 1/3 of the slaughterhouses in the United States. Temple Grandin understands and relates more easily to cattle than to people. She's renowned for her design "stairway to heaven," a curving, high-wall ramp system that utilises optical illusions to lead livestock calmly from the pen to the bolt gun and ultimately to a humane death.
