Up first, Stanford medical professor Daria Mochly-Rosen argues that the tiny machines inside our cells — mitochondria — are quietly running the show, and that taking care of them can change how we feel, age, and function. Her book is The Life Machines: How Taking Care of Your Mitochondria Can Transform Your Health. And later, surgeon general nominee Casey Means connects metabolism to almost everything we care about—from mood to chronic disease—by sharing big ideas from her 2024 book Good Energy: The Surprising Connection Between Metabolism and Limitless Health.
