The 12 Hallmarks of Aging
First systematized by López-Otín et al. (2013, updated 2023), the hallmarks are the molecular and cellular mechanisms that cause organisms to age. Understanding them is the prerequisite for any rational anti-aging protocol.

Scientific Foundation
The hallmarks framework was first published in Cell 2013 (PMID: 22768836) by López-Otín et al. and expanded to 12 hallmarks in the 2023 update (PMID: 36599349). TNiC maps interventions to this framework using Tier A/B/C evidence grading. The hallmarks are a descriptive framework, not a complete mechanistic theory — causality between hallmarks is bidirectional and context-dependent.
