A technical read on epigenetic clocks, blood-chemistry clocks, and survey-based 'bio age' calculators: what each one measures, how precise it is, and how to compute one yourself from your own data.

Three different things get called a DNA clock. This page covers the one people usually mean, the epigenetic age clock: which assay to run, how to compute the score yourself from IDAT or bedMethyl files, and how much of the number is signal.

A practical protocol for estimating functional age from physical performance tests, blood chemistry algorithms, and DNA methylation clocks, with the reliability problems that make most single-timepoint results uninterpretable.
