The epigenetic clock leads to a chronological age prediction that has a Pearson correlation coefficient of r = 0.96 with chronological age (Figure 2 in). Thus the age correlation is close to its maximum possible correlation value of 1.
Horvath’s chronological age is 56 and is a self-described “health nut,” and the lowest it dipped recently was 52. During one year when his GrimAge was three years higher than usual, he ...
