It’s easy to feel the urge to turn back time as you watch the years quickly pass you by. Luckily, your chronological age (i.e., how old you are) may not be what defines your vitality. The concept of biological age is another way to consider how old you are, and it doesn’t involve looking at how many years you’ve lived.
Chronological Age vs. Biological Age: What’s the Difference?
You may be surprised to hear that you actually have two ages – a chronological age and a biological age. Chronological age describes the number of years you’ve been alive, while biological age looks at the condition of your cells to determine how they have changed since you’ve been alive.
Biological age looks at various measurements of biomarkers to determine the state of your health. Your biological age might reflect your lifestyle factors, genetics, demographics, and diet. Every human’s body ages at a different rate, and biological age can help you see how quickly or slowly your body is aging.
Evaluating your rate of aging on a cellular level can give insight into whether you’re aging at a standard rate or your body is aging faster or slower than expected. Calculating biological age may help you realize that you need to adjust certain factors to help slow or even reverse your current rate of aging.
