How Does the Epigenetic Clock Actually Work?

We all know our chronological age, but what if your body is aging at a different speed than your calendar suggests? Scientists are increasingly using the 'epigenetic clock' to study the molecular changes that happen inside our cells as we get older. In this video, we break down the science of DNA methylation—the chemical process that allows researchers to estimate biological age. We look at the landmark research, including the Dunedin Study, that helped scientists understand why some people's biology seems to age faster than others. We also discuss the limitations of these tests. While these biomarkers provide a fascinating look at systemic health, they aren't a crystal ball for your future health. Learn what the science actually says about measuring aging and why this field is changing the way we look at human longevity. If you enjoy evidence-based science and want to understand how our bodies change over time, this one's for you.
