One of the reasons for the success of 99X is the nostalgia factor. What's going on in our brains when we're feeling nostalgic? Our guest, Dr. Hal McDonald is here to talk about what happens in our brain when we hear a song we love that's 30 years old.

Hal McDonald, Ph.D., a professor of literature and linguistics at Mars Hill University, is the author of the medical mystery The Anatomists. His article about nostalgia is HERE.
