Answer: continuity theory
Step-by-step explanation:
The continuity theory of aging according to George Maddox states that as middle and older adults age, they will preserve and maintain existing patterns or activities by using familiar knowledge to make adaptive choices in their life,
for example even though Mr Zietz is a retired drama teacher, he still spends a lot of his time volunteering at a local community theater and also enjoys weekend trips to see plays with his former colleagues. Mr. Zietz's activities are consistent with the Continuity theory of aging.
