Ageing (British English) or aging (American English) is
the accumulation of changes in a person over time.
Ageing in humans refers to a multidimensional process
of physical, psychological, and social change. Some
dimensions of ageing grow and expand over
time, while others decline.
AIMS AND OBJECTIVES
Ageing is the single greatest challenge our society is
facing today. Recent breakthroughs have
demonstrated that it is possible to combine a long life
with the absence of age-related disease.
THEORIES OF AGEING
Wear and tear theory
Genetic mutation theory
Free radical theory
Social exchange and support
The concept of successful ageing can be traced back to
the 1950s, and was popularised in the 1980s.
Successful ageing consists of three components.
1.Low probability of disease or disability.
2.High cognitive and physical function capacity.
3.Active engagement with life.

From these above discussions we can conclude
We all change physically, as we grow older.
Steps can be taken to help prevent illness and
injury, and which help maximize the older
person's independence, if problems do occur.
There is no need for most people to fear getting
