Biological age

Biological ageing refers to the decline in tissue/organismal function, whereas chronological ageing simply indicates the time passed since birth. In normally ageing individuals, chronological age equates to biological age. 

The observation that individuals do not age at the same pace led to the concept of biological ageing, also called functional or physiological ageing. Whereas chronological ageing refers only to the passage of time, biological ageing relates to decline in function.
