This complete, honest guide separates real science from hype. It covers the biology of aging, lessons from the world's longest-lived populations, and the well-established pillars of healthy longevity: nutrition, exercise, sleep, stress management, and social connection. It also offers a clear-eyed, critical look at intermittent fasting, longevity supplements, and cutting-edge research like senolytics and rapamycin — what's promising, what's overhyped, and what remains unproven.
Written in clear, evidence-based language that never overstates the science, this book helps readers build a realistic, sustainable plan for extending not just their lifespan, but their healthspan — the years lived in genuine vitality.
