In this essay I am going to discuss two psychological/sociological theories and one biological theory of ageing and then I will compare one psychological theory of ageing with the chosen biological theory of ageing.
The first sociological/psychological theory I am going to explain is the disengagement theory. This theory suggests that as we get older we begin to withdraw from society.
