The disengagement theory states that the normal way to age is to cut down in activities and commitments to others and become increasingly preoccupied with the self.
Step-by-step explanation:
The theory that states that the normal way to age is to cut down in activities and commitments to others and become increasingly preoccupied with the self is the disengagement theory. This theory suggests that withdrawing from society and social relationships is a natural part of growing old. It argues that as individuals approach death and experience physical and mental decline, it is natural for them to withdraw from others. According to this theory, social withdrawal allows greater freedom from social norms and pressure to conform.
