Old man Henry comes to life with the sound of music

Science tells us that humans are hard-wired to respond to music. What better proof than to watch the magic spell it casts on Henry, an old man languishing in a nursing home? In this video, a trailer for "Alive Inside," a new documentary featuring famed neurologist Oliver Sacks, Henry sits in a wheelchair, depressed, dead to the world around him. Then he's given some ear phones, and the music from his era begins to play. Instantly, he lights up. His eyes pop open wide and his body begins to rock. Henry is no longer in the present. The music has transported him back. For a moment in time, he's young again.
