Key points from article :
Four genetic and molecular biomarkers have been identified over the past decade for predicting longevity.
Telomeres length, gene methylation, polygenic risk, 14 blood-based metabolism markers are longevity biomarkers.
Slower the rate of telomere shortening is, the longer that individual is likely to live.
Increased level of gene methylation was correlated with shortened longevity.
Several companies are already offering consumers tests to assay their telomere length.
