The relationship between physical activity and aging is significant. Engaging in regular exercise can mitigate the physical and cognitive declines associated with aging. Active individuals tend to experience enhanced muscle strength, improved balance, and better flexibility, reducing the risk of falls and injuries. Furthermore, physical activity can maintain or improve bone density, helping to prevent osteoporosis. Regular exercise has also been linked to better mental health, as it can diminish the incidence of cognitive decline and depression. Overall, staying active promotes longevity and improves the quality of life in older adults.
