Biomarkers of ageing

Biomarkers of ageing are special signs in our body that tell us how old we are. They show us things about our health, and can even help doctors predict when we will get older. Biomarkers are usually seen in things like our blood, skin, and even our DNA. For example, doctors can look at our blood and see if certain molecules, like proteins, are present or not. They can also see if certain genes in our DNA have changed over time, which can show us how our bodies have aged over time.
