This past July, famed neurologist Oliver Sacks turned 80. Writing in The New York Times, the day before his birthday, he expressed his joy at being old. "I do not think of old age as an ever grimmer time that one must somehow endure and make the best of," he said. “But as a time of leisure and freedom ... free to explore whatever I wish." For decades, Dr. Sacks has written about the mysteries of the human brain in his 12 books. His most recent is “Hallucinations," an account of his patients’ experiences -- and his own from the use of mind-altering drugs as a younger man. Oliver Sacks joins Diane to talk about his decades-long career exploring the mysteries of the brain.
