Biological Age vs. Chronological Age—Why It Matters
We all want the same thing: the chance to live a full, rich, active life for as long as we can. Unfortunately, time only moves in one direction. Traditionally, most people have thought of the aging process as equally fixed. But longevity researchers have developed an exciting new framework for thinking about aging that offers hope now … and even more in the future.
The key is knowing we have two different ages:
Our chronological age is what it sounds like – the literal number of years we’ve been alive. There’s no going back on this one.
Our biological age refers to how old our physical cells are. It turns out we have some control here!
Understanding biological age is helping longevity science unlock the secret to why some people of similar chronological ages have much longer healthspans – periods of life where they enjoy their chosen life adventures free of aging-related diseases.
