Corrected the 2023 Hallmarks framework from 14 to 12 processes, expanded the mitochondrial-dysfunction explanation, and stated that no standardized consumer assay measures whole-body mitochondrial health. A separate clock guide now explains population-level non-linear aging findings while distinguishing cross-sectional and short longitudinal studies from one person’s life-course trajectory.
The Hallmarks count was factually wrong, and exact age-wave findings could be misread as universal personal thresholds without their design limits and the study’s later editorial note.
Readers see the correct framework and a more cautious interpretation of reported aging transitions; no clinical decision is presented as depending on a particular age threshold.
