In this short monologue, neurologist Dr. David Perlmutter explains that sedentary behavior can be split into two categories: passive activities that do not stimulate the brain (e.g., watching TV, doom‑scrolling) and mentally engaging activities that challenge the mind (e.g., puzzles, card games, reading). He cites a recent study linking passive sitting to a higher risk of cognitive decline, while highlighting research showing that cognitively demanding sedentary tasks are protective. Dr. Perlmutter concludes with practical advice: when you sit, choose activities that actively engage your brain to support long‑term cognitive health.
