Aging sounds like something that people should be able to read at a glance, but the human body doesn’t offer a simple, visible stamp that reliably tells us how much time has passed. Instead, our “timestamps” are tucked inside us, written in tiny ways that scientists are trying to decode.
Experts have been attempting to learn how to track biological aging in the hopes of understanding how people age and what could potentially be done to stop it. Intrigued? Read on to see which common biological markers scientists are trying to use to measure aging.
