What is the person-environment fit theory of ageing and how does it affect well-being?

Developed by M. Powell Lawton and Lucille Nahemow in the 1970s, the **person-environment fit theory of ageing** posits that an older adult's quality of life and behavior are a function of the congruence between their personal competence and the demands of their environment. This theory has become foundational in environmental gerontology for understanding how older adults interact with their surroundings.
