Final answer:
Evelyn might consider engaging in writing, painting, sculpting, crosswords, jigsaw puzzles, or chess to preserve mental sharpness. These cognitive activities can help maintain cognitive function and delay cognitive decline.
Step-by-step explanation:
If 60-year-old Evelyn wants to increase her chances of preserving mental sharpness, she might consider taking up activities such as writing, painting, or sculpting; crosswords or jigsaw puzzles; or mentally challenging games like chess. Engaging in these activities can be beneficial in maintaining cognitive functions, as they help to exercise both crystallized and fluid intelligence, which may thwart cognitive decline and contribute to the maintenance of mental acuity into late adulthood. Research suggests that adults who engage in both mentally and physically stimulating activities experience less cognitive decline. This is supported by studies which indicate that cognitive rehabilitation and exercises, like solving puzzles and participating in challenging games, can delay the onset of cognitive impairment. Moreover, adopting a healthy lifestyle that incorporates frequent physical exercise can enhance cognitive function and possibly reduce the risk of dementia.
