The Biology of Aging and Epigenetics

Why We Age, the Hallmarks of Aging, and the Evidence-Based Science of Healthspan

The Biology of Aging and Epigenetics is Book K1 of The Performance & Human Physiology Encyclopedia — a 93-volume, university-level library on what genuinely extends healthspan, and what is being sold to you. It is written for longevity-minded readers, biohackers and clinicians who want the evidence: deep enough that a professional already trained in the field keeps learning, structured clearly enough that a motivated reader can follow every step.

How this book is written

• University level, without dilution. Exact scientific terminology, defined at first use — mechanisms, not just conclusions.
• Evidence graded, not asserted. Major claims carry a level, from A (strong) to D (expert opinion), so you always know how much weight to give them.
• Numbers, formulas, worked examples. Reference ranges, equations and solved calculations you can apply the same day.
• Myths confronted directly. Where a popular claim does not survive the evidence, the book says so — and shows why.
• Fully referenced (APA 7). References at the end of every chapter, plus a master bibliography.
