Ageing is the accumulation of changes in an organism or object OVER time. Ageing in humans refers to a multidimensional process of physical, psychological, and social change. Some dimensions of ageing grow and expand as time goes by , WHILE others decline. Reaction time, for example, may slow WITH age, whereas knowledge of world events and wisdom may expand. Research shows that EVEN late in life potential exists for physical, mental, and social growth and development. Ageing is an important part of all human societies reflecting the biological changes that occur, but also reflecting cultural and social conventions. Age is usually measured IN full years — and months for young children.

The term “ageing” is RATHER / QUITE / VERY / EXTREMELY ambiguous. Distinctions may be made between “universal ageing” (age changes that ALL people share) and “probabilistic ageing” (age changes that may happen to some, but not necessarily everybody as they grow older, SUCH as the onset of Type Two diabetes). Chronological ageing, REFERRING to how old a person is, is arguably the most straightforward definition of ageing and may be distinguished from “social ageing” (society’s expectations of how people should act as they grow older) and “biological ageing” (an organism’s physical state as it ages).

Differences are sometimes made between populations of children;divisions are sometimes made between the young old (65-74), the middle old (75-84) and the oldest old (those aged 85 and above). However, sometimes chronological age does not correlate perfectly with functional age, i.e. two people may be of the same age, but differ IN their mental and physical capacities.



  1. This post appears to refer to ageing only within an objective context. I would argue that subjective ageing is more important in its impact on our lives and our sense of wellbeing. Find out more at
