TL;DR: The major locus determining familial longevity up to high age as detected by GWAS was marked by rs2075650, which tags the deleterious effects of the ApoE ε4 allele, and no other major longevity locus was found.

TL;DR: It is observed that a younger biological age associates with lower levels of p16INK4a positive cells in human skin, and this data indicates that middle‐aged individuals with the propensity for longevity are more likely to have fewer senescent cells.

TL;DR: It is indicated that women who look young for their age have large lips, avoid sun-exposure and possess genetic factors that protect against the development of gray hair and skin wrinkles.

TL;DR: Perceived age—which is widely used by clinicians as a general indication of a patient’s health—is a robust biomarker of ageing that predicts survival among those aged ≥70 and correlates with important functional and molecular ageing phenotypes.

TL;DR: For instance, this article found that the likelihood that the older looking twin of the pair died first increased with increasing discordance in perceived age within the twin pair, that is, the biggerthe difference in perceived ages within the pair, the more likelythat the older-looking twin died first.
