Your Biological Age and Chronological Age May Differ
You might have heard that age is but a number—and that might be true. The human body has a chronological age, starting from the day you are born, and a biological age, that is separate from your chronological age. In other words, your biological age shows low slow or how fast your body is decaying and growing older. Lifestyle choices, such as activity levels, diet, smoking, drinking alcohol, and diseases will affect your biological age.
The reason for this would be telomeres, found at the end of chromosomes. When cells in the body divide, the telomeres start to unravel. Shortening telomeres are just one theory beyond aging, since shorter telomeres often correlate with graying hair, wrinkles, higher incidences of illness, and so on. That is why a healthier person might look like they are in their late twenties when their chronological age is 40 or why a man who smokes heavily looks 65 when he is really 35.
