Aging is inevitable, but how we age is within our control. Scientific advancements have given us unprecedented insight into the biological mechanisms of aging, offering us the ability to extend not just our lifespan, but our healthspan—the number of years we remain healthy, active, and mentally sharp. This book provides science-backed, actionable longevity hacks designed to help you optimize your health, energy, and vitality.

The problem today is that longevity advice is scattered. The sheer volume of information available can be overwhelming, and much of it is contradictory, misinterpreted, or not rooted in solid science. The longevity space is like the wild west—full of trends, misinformation, and marketing hype. For the average person, it’s hard to separate the signal from the noise.

That’s where this book comes in. This is a no-nonsense, straightforward summary of key learnings from the best experts and sources. Instead of spending countless hours sifting through research papers, podcasts, and self-experimentation blogs, you’ll get practical, research-backed longevity strategies distilled into easy-to-follow, daily habits. Each hack is concise, actionable, and rooted in science—so you can immediately apply it to your life.

This book is primarily based on Western longevity science and research, drawing from the latest findings in geroscience, metabolic health, exercise physiology, and neuroscience. It references leading experts in the field, including Peter Attia, Andrew Huberman, Bryan Johnson, David Sinclair, and Michael Greger. 

However, longevity is not just a biological pursuit—it’s also deeply cultural and philosophical. That’s why this book also draws inspiration from the Far East, particularly Japanese concepts that emphasize purpose, resilience, and mindful living. You’ll see these influences especially in Chapter 2 (Nutrition Hacks for Longevity) and Chapter 5 (Stress, Mindset, and Longevity), where practices like following the "Hari Bachi Bu" rule of eating only until you're 80% full, balancing your plate with the five elements (Wood, Fire, Earth, Metal, and Water), "Shinrin-Yoku" (forest bathing), finding your "Ikigai", and engaging in "Zuihitsu" journaling offer powerful tools for mental and emotional longevity.
