12. Rewiring the Mind: The Science of Neuroplasticity

For decades, scientists believed that once we reached adulthood, our brain development stopped. We now know that isn't true. In this episode, based on Chapter 12 of Live Long, Healthy and Happy, we explore neuroplasticity—the brain's incredible ability to form new connections and physically reshape itself at any age.Tune in to discover:• The Muscle Metaphor: Why the brain, like a muscle, requires challenge and novelty to stay strong and prevent atrophy.• Cognitive Reserve: How learning new skills builds a "backup system" of neural pathways that can delay the symptoms of aging and dementia.• Beyond the Classroom: Why you don't need a degree to keep your brain young—learning an instrument, a new language, or even a new game offers the same biological benefits.• The Growth Mindset: How to overcome the fear that you are "too old" to learn and embrace curiosity as a survival skill.
