James Kennedy interviews neuroscientist Dr. David Cox about his book The Age Code, covering how to lower your biological age through simple, science-backed habits like eating earlier, getting more fiber and omega-3s, and cutting back on ultra-processed foods

James Kennedy speaks with evolutionary biologist, author, and editor Dr. Rowan Hooper about his book Togetherness. They explore how symbiosis drives complex life—from leafcutter ants and underground fungal networks to the human gut microbiome—while challenging "survival of the fittest" stereotypes to advocate for a cooperative relationship with the natural world

James Kennedy speaks with neuroscientist and author Dr. Joseph Jebelli about his book The Brain at Rest. They discuss how overwork and constant digital stimulation harm cognitive health, and explore how activating the brain's default mode network through true rest—such as nature walks, daydreaming, napping, and short breaks—enhances memory, creativity, and long-term productivity

Host James Kennedy interviews neuroscientist Dean Burnett, who explores how human emotions, modern mental health challenges, and brain adaptability intersect. Burnett discusses how primitive stress responses mismatch our digital world, how neuroplasticity and psychedelics aid mental health, and why embracing negative emotions is vital for well-being.
