Cracking the Aging Code

Theoretical biologist Josh Mitteldorf and writer Dorion Sagan take a genuinely provocative position: aging is not simply wear and tear but a programmed evolutionary mechanism that stabilizes populations. That thesis alone earns this book a serious read, and the authors back it up with impressively broad scientific coverage across multiple species. BookPage praised its comprehensiveness, and the writing stays accessible for a topic that could easily turn impenetrable. The honest caveat is that some claims are overstated and the subtitle — which hints at practical longevity tips — oversells what is primarily a theoretical argument. If you go in expecting a science-of-aging deep dive rather than an action plan, you will find it genuinely thought-provoking.
