How to Protect Your Brain as You Age — Cognitive Reserve, Focus, and What Actually Matters
Season 1 Episode 105
What really keeps the brain sharp as we age — and what quietly puts it at risk?
In this episode of the Ageless Athlete Podcast, host Kush Khandelwal speaks with Dr. Tommy Wood, neuroscientist, physician, and strength athlete, about the science of cognitive reserve and why long-term brain health depends on challenge, learning, and effort — not comfort or flow.
Flow states feel rewarding, but as Dr. Wood explains, they don’t create the kind of stimulus the brain needs to adapt over decades. Instead, the brain thrives when it’s pushed to learn new skills, navigate uncertainty, and stay engaged through physical movement, mental effort, and diversified identity.
This conversation connects neuroscience, exercise science, and psychology in a practical, accessible way — especially for adults who care about aging well, staying mentally sharp, and maintaining performance into midlife and beyond.
