Key points from article :
A new clock 'GrimAge' is a strong predictor of all-cause mortality - the likelihood of dying from any cause.
490 people were tested for eight metrics which included some physical and cognitive tests.
4 different clocks including GrimAge were used.
The cohort was investigated for predictors of health outcomes and factors known to affect health.
GrimAge predicted 7 of the 8 tested items.
It was very successful at predicting all-cause mortality, and none of the other clocks came close.
GrimAge may be a useful clinical endpoint for testing the efficacy of rejuvenation therapies.
Even more efficient epigenetic clocks can be developed in the future.
A variety of clocks trained on individual age-related conditions and diseases may be developed soon.
