Chronological Age Vs. Biological Age
There are two different ages in the human body, a chronological age, and a biological age. The calculator further down the page provides you with your chronological age.
- Chronological Age - Signifies how old you are and is defined as the number of years you have lived from the time you were born. Your age is used frequently throughout life to determine such things as; when you are eligible for school, work and retirement. Or how many days until you reach legal drinking, voting age etc. We also have a handy chart showing average life expectancy listed by country and gender.
- Biological Age - A concept used loosely, and with little objectivity, to describe a shortfall between a population cohort average life expectancy and the perceived life expectancy of an individual of the same age. Biomarkers of aging are biomarkers that better predict functional capacity at a later age than chronological age. Stated another way, biomarkers of aging would give the true "biological age", which may be different from the chronological age. Disabled World also provides you with a free calculator to calculate your biological age.
