(Audio) Super Agers, by Topol

Wednesday July 1, 2026

Dr. Topol offers his adult-in-the-room response to such books as Attia's Outlive and Sinclair's Lifespan. He specifically recommends against taking rapamycin, for example, and doesn't (as far as I could tell) use misleading graphs the way Attia did. He does throw around words like "sequelae" and "senolytics" and narrate the audio book himself.

He pronounces GLP-1 as "glip one" and really likes it, and really likes AI, and mentions very many times that the gut microbiome is connected with everything, and thinks we should use waist circumference more in medical contexts.

One interesting connection that caught my attention was that he related pleiotropic genes (genes that cause multiple things, and we don't always know why or how) and AI explainability (a model does something, and we don't always know why or how). I think the broader point was that in medicine, we don't always know the mechanism by which something (some drug, etc.) works, and we're satisfied if it does work. Maybe AI is not so different.

In the end the book mostly has the same core recommendations for healthspan that everyone knows: eat healthy, exercise, etc. It has a lot more detail, on a wide range of things, and is really long, compared to some of the other pop live-forever books. It's reserved in its predictions of longevity breakthroughs. It's "an evidence-based approach to longevity."
