Dr. Mills sits down with cognitive neuroscientist, musician, and bestselling author Daniel Levitin for a wide-ranging conversation on the brain, music, and what it really means to age well. From the science of dopamine and why music can literally rewire the brain to the difference between lifespan and “healthspan,” Dr. Levitin breaks down complex ideas with the same clarity that made 'This Is Your Brain on Music' a modern classic. He also shares insights from his latest book, 'I Heard There Was a Secret Chord,' including powerful stories about music’s role in healing and recovery. It’s a deep, funny, and unexpectedly moving look at how curiosity, creativity, and a great song might just be the keys to a longer, better life.
