How Old Do I Look?
While some people look their age, others do not.
While some people look their age, others do not. One way of measuring this discrepancy involves differentiating between “chronological age” (how old the calendar says we are) and “biological age” (the age at which the body functions compared to average fitness or health levels). When people say that “age is just a number,” they are correct in that chronological age doesn’t really reflect how old a person actually is. Instead, biological age is the number that really counts, because it determines our health and, ultimately, our lifespan. We all age biologically at different rates in accordance with our genes, what we eat, how much we exercise, the quality of our sleep, and the level of stress we endure.
P.S. Unlike chronological age, it is possible to turn back biological age by adopting a healthier lifestyle.
