2. INTRODUCTION
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.
3. 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.
4. THEORIES OF AGEING
Biological Theories
Wear and tear theory
Cellular theory
Auto-immune theory
Genetic mutation theory
Free radical theory
Psychosocial Theories
Disengagement theory
Activity theory
Continuity theory
Social exchange and support
Gero-transcendence
Socio-emotional selectivity
5. SUCESSFUL AGEING
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.
7. PREMATURE AGEING DISEASE: PROGERIA
Progeria (Hutchinson-Gilford
Progeria
Syndrome, HGPS, Progeria
syndrome) is an extremely rare
genetic disease wherein
symptoms resembling aspects of
aging are manifested at a very
early age.
The disorder has a very
low incident rate,
occurring
in an estimated 1 per
8 million live births. It is
a genetic condition
that occurs as a new
mutation, and is rarely

12. CONCLUSION
From these above discussions we can conclude
that:
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
older.
