Final answer:
Engaging in mentally and physically stimulating activities can help delay cognitive decline in late adulthood. Aerobic exercise has cognitive benefits and improves various cognitive functions such as attention, memory, and problem solving.
Step-by-step explanation:
In late adulthood, there is a decline in fluid intelligence, which includes information processing abilities, reasoning, and memory. However, research has found that engaging in mentally and physically stimulating activities can help delay the onset of cognitive decline. Adults who participate in these activities show less cognitive decline and have a reduced incidence of mild cognitive impairment and dementia. For example, aerobic exercise has been shown to have cognitive benefits and can improve attention, working memory, cognitive flexibility, inhibitory control, problem solving, decision making, and information processing speed.
