Task 3 - Theories of ageing.
By Aisha Small
What is old age?
Sociological & Psychological types:
Social creation of dependency.
Disposable soma theory.
This theory combines the apparent declining force of natural selection after breeding age is reached with accumulation of damage, and suggests a relationship between reproduction and life span while avoiding conflict with traditional evolutionary mechanics theory.
Genetically programmed theory.
In short this means that we are programmed to age and die.
