Suppose A new study shows that regular exercise can improve mental health and cognitive function in older adults. The research, conducted over a period of two years, found that participants who engaged in physical activity three times a week showed significant improvements in memory, attention span, and overall mood. The findings suggest that staying active can help prevent age-related cognitive decline and enhance quality of life in older individuals.
Can we infer that "Regular exercise has no impact on mental health and cognitive function in older adults."? Yes, no, or maybe?
