100

Dr Mark Hyman talks with patients and followers every day who want his advice. Their goal: to live to 100 and stay healthy. But as Hyman explains, it's not that simple. We don't live in perfectly controlled environments.

In 100: HOW TO LIVE 100 HEALTHY YEARS, Hyman bridges the gap between the experience of daily life and the often-invisible biological forces shaping energy, cognition, metabolism, immunity, and emotional well-being.

Each chapter focuses on one of what he calls the Main Domains of daily life -sleep, gut health, movement, weight, mental health, nutrition, and environmental health, and looks at:
·What it shapes (your systems and biomarkers)
·What goes wrong (early signals and common symptoms)
·What the labs show (biological data we can track)
·What we miss (myths, blind spots, and cultural noise)
·What to do (simple, non-dogmatic suggestions to begin recalibration)
·Stories of patients he has worked with
·Authentic insights from evidenced based research

The goal? To help readers reconnect with their biology-not through shame or perfectionism, but through self-awareness, curiosity, and empowered noticing. Once we understand what 'healthy' actually looks like, we can begin to set up our lives to attain it. And yes, use that information to extend our lifespan. Living to 100 years is, truly, within our grasp.
