Can we objectively tell how fast we are aging? With a good measure, scientists might be able to change our rate of aging to live longer and healthier lives. Researchers know that some people age faster than others and have been trying to concisely measure the internal physiological changes that lead to deteriorating health with age.

For years, researchers have been using clinical factors normally collected at physicals, like hypertension, cholesterol and weight, as indicators to predict aging. The idea was that these measures could determine whether someone is a fast or slow ager at any point in their life cycle. But more recently, researchers have theorized that there are other biological markers that reflect aging at the molecular and cellular level. This includes modifications to a person’s genetic material itself, or epigenetics......
