Most discussions about aging focus on lifespan. Yet what matters to most of us is brainspan — how long our mind remains sharp, resilient, and wise. Explore how the brain ages naturally and unnaturally, and what the latest science reveals about protecting memory, balance, and clarity. Look at the difference between normal cognitive changes and early signs of dementia, while emphasizing practical, evidence-based prevention strategies. Topics include brain function and neuroplasticity, how brain shrinkage affects falls and sensory health, the role of nutrition and supplements in fueling cognition, and the impact of sleep, stress, social ties, and purpose on long-term resilience. Each session combines accessible science, simple self-tests, and engaging take-home practices.
