Your double helix is ticking.

We can do a lot to shorten or lengthen our time on earth, from what we choose to eat, to where we choose to live. But some part of our longevity is hardwired. It’s dictated by our genes.

Scientists have discovered a human “biological clock” based on certain changes to genes, called DNA methylation. These are important for the expression and deactivation of genes, and therefore our development. By studying DNA methylation markers, the researchers found a way to predict lifespan. When people had a biological age greater than their actual age (you could be 50, but have the DNA of a typical 75-year-old), they could see they were more likely to die sooner than a person whose biological and real ages were similar.

Some DNA methylation changes are lifestyle-related, but enough are hereditary for forecasting purposes.
