HOW OLD ARE YOU REALLY?

How old am I really? The calendar says I just turned 66, but how I feel and what I can still do compared to my peers points to a much younger age. The calendar doesn’t lie, however, to get the full story we need to understand our biological age. Also known as our physiological or functional age, biological age differs from chronological age because it takes into consideration a number of factors other than just the day you were born.
