Neurologist Dr. Guy Leschziner, author of 'The Nocturnal Brain,' says sleep is not a binary state, and the brain can be in multiple stages of sleep at once. That can explain why people sometimes walk, eat, and even have sex while sleeping. He talks about insomnia, medication, and some of the more unusual disorders he has treated.
Also, we remember Paul Krassner, who died July 21. He published and edited the magazine 'The Realist' from 1958 until 1974 and became known as "the father of the underground press."
