How It Works

Popular-science synthesis of Sinclair's research narrative — not a clinical manual. The book catalyzed consumer interest in NMN/NR, resveratrol, and aging-as-treatable framing worldwide.

1

Information Theory of Aging

Aging as loss of epigenetic information — cells forget how to read the correct gene program.

2

Longevity Pathways

Sirtuins, AMPK, mTOR, and NAD+ as levers you can influence with diet, exercise, and precursors.

3

Lifestyle Roadmap

Intermittent fasting, exercise intensity, cold exposure, and polyphenol-rich eating from the book's practical chapters.
