That is, your chronological age, which measures how many years have passed since you were born, may not match your biological age, which reflects wear and tear on your body at a cellular level.

Based on factors including genetics, lifestyle habits and medical history, you may be biologically older or younger than your chronological age. That’s because these two measures don’t always progress at the same pace, according to Dr. Douglas Vaughan, director of the Potocsnak Longevity Institute at Northwestern University’s Feinberg School of Medicine.

“Every time you have a birthday, you add another year to your life,” Vaughan said. “We all experience that at the same rate, and it’s relentless, it’s unforgiving, it’s cosmically indifferent.”
