There was a show on Steven Hawking 3 or 4 months ago that described his life story, focusing on his theories about black holes and how these progressed over time. ALS was definitely part of the presentation, and they demonstrated how he worked with an assistant to accomplish his work in astrophysics even after he was completely paralyzed. My son was really interested in the science content, and was continually annoyed by my mother and I discussing the progression of his ALS and trying to figure out if he was on a vent.
