John Elder Robison, whose younger brother is the writer Augusten Burroughs, did not get his diagnosis of Asperger's until he was in his 40s. He tells Anne Strainchamps how he manages to function in society, and what he remembers from the household chronicled in his brother's book, "Running with Scissors." John Elder Robison's memoir is called "Look Me in the Eye: My Life with Asperger's."
