Brain at 100+ Pol Grek — Excerpt — Brain at 100+ A science-backed plan to keep your mind sharp for decades Most people assume the brain will “just hold on” until retirement. Brains don’t work that way. Cognitive longevity isn’t a lottery ticket or a genetic sentence. It’s the sum of daily choices that either build reserve — or slowly burn it down. This book isn’t about becoming a genius in a week. It’s about not losing clarity while you’re busy with “more important” things. Most longevity talk sells supplements. The boring levers win: sleep architecture, movement that raises heart rate, blood pressure, blood sugar, and hard thinking that builds reserve. Skip the genius-in-a-week pitch. Protect clarity while you run a real life. — © Pol Grek / Пол Грэк Full text: Amazon and/or LitRes product pages linked from polgrek.site/en/ Educational sample only — not medical advice.
