Andrew Steele
Ageless (Hardcover)
Ageless by computational biologist Andrew Steele — a clear tour of the 10 hallmarks of aging, senolytics, and treating biological aging as a solvable medical problem.
Steele on treating aging as biology — not another Sinclair stack cookbook
Computational biologist Andrew Steele’s 2021 tour of hallmarks, senolytics, and why aging itself is the risk factor. More lab than kitchen. Pair with Sinclair and Topol; you do not need NMN to finish the book. Hardcover ASIN 0385544928 is in the buy box.
Typical price: $16 – $30 USD
How It Works
Geroscience for civilians. Strongest on why aging is a target. Weakest as a shopping list — we do not turn hallmarks into a 12-bottle cart.
Aging as Cause
Cancer and heart disease ride on aging biology. Treating only the downstream disease is the 20th-century play.
Hallmarks, Not Hashtags
Senescence, mitochondria, immune aging. See fisetin and NAD guides for the supplement version — this book is the why.
Not a Protocol
Steele is a map of research. Attia and walking still do more this year than a senolytic tweet.
What You'll Experience
Reading
2 weeksMost readers book a physical and an ApoB, then keep lifting.
After
MonthsIf you only bought NMN, you missed the point.

Risks & Considerations
Research, Not a Pharmacy
high riskDo not source senolytics from a telegram because a hardcover named the pathway.
2019–2021 Snapshot
low riskGLP-1s and 2025 clinic news live in Topol, not here.
Community Reviews
Synthesized consensus from Reddit, forums, and expert sources.
Praised as clear and serious. Some wanted more ‘what do I do Monday.’ The hallmarks chapters are the part people cite.
