The age on your driver’s license may not be exactly correct — well, for certain parts of your body anyway.

A new study, published Monday in peer-reviewed journal Genome Biology, suggests that we all have an internal biological clock that tracks the aging process — and may reveal the true age of our cells and tissues. It’s hidden right in our DNA.

“The epigenetic clock really allows someone to objectively measure the age of cells and tissues,” study author Dr. Steve Horvath, a professor of human genetics and biostatistics at the University of California, Los Angeles, told The Huffington Post. “Therefore, it can be used to study aging.”

This internal “timepiece” may also be used to compare the various ages of elements in the body. For instance, in his research, Horvath found that female breast tissue ages several years faster than the rest of the body, which may explain why breast cancer is the most common cancer in women. Cancer also greatly accelerates the age of affected tissues.
