Fe at u re s D IS C U S S IO N Definition of ageing Ageing involves a decrease in the ability of an organism to cope with living in a particular environment. The deleterious age-related changes are cumulative. Ageing is therefore an intrinsic property of living organisms. Ageing is natural and should not be considered as a disease. It cannot be cured but maybe in future, depending on the state of knowledge, the changes might be reversed or be prevented or delayed.
