Biological Age Test: What Epigenetic Clocks Measure and What Your Results Actually Mean
Your birth certificate says one thing. Your cells might say something different. Biological age tests analyze chemical tags on your DNA to estimate how quickly your body is aging relative to your chronological age. The field has evolved rapidly since the first epigenetic clocks were published in 2013, and the latest generation of tests can now predict disease risk and mortality with surprising accuracy. But the science is more nuanced than most longevity podcasts suggest, and understanding what these tests can and cannot tell you matters before you order one.
