Final answer:
Meghan would discuss the activity theory, which advocates for the benefits of social and physical engagement in leisure activities for greater happiness and life satisfaction, as well as potential economic savings and earlier retirement.
Step-by-step explanation:
Meghan is likely to mention findings that support the activity theory, which suggests that involvement in leisure activities and social engagement are critical to happiness in later life. The theory posits that an active lifestyle can be a key to increased satisfaction, as exemplified by the older woman who, upon retiring, engages in various social and leisure activities. Given the increased time afforded by labor-saving devices and the sedentary tendencies of some modern leisure activities like computer games, Meghan might urge middle-aged adults to actively seek out more physically and socially engaging pursuits. This could include sports, hobbies, or community involvement, which have been shown to contribute to a more fulfilling lifestyle, potentially leading to savings and an earlier retirement.
