What Sitting All Day Does to Your Brain and Body | Keith Diaz | TED

Can a five-minute walk change how you feel all day? Exercise scientist Keith Diaz shows how your body is built for the kind of movement that modern life has quietly erased — and suggests something refreshingly doable: making time for small doses of movement sprinkled throughout the day, as a way to boost your brain and body. (Recorded at TED2026 on April 15, 2026)
