Whether we’re musical or not, we’ve all got rhythms. Circadian rhythms. Those are our internal biological software that keeps all the magical devices in our bodies functioning in a 24-hour day. All creatures have them, yet humans tend to abuse theirs. Emily Manoogian is a Chronobiologist and Clinical Researcher at The Salk Institute. She’s a Circadian evangelist and joins host Steve Fisher to explain why we need to dance to our internal music.
