Physical fitness significantly contributes to longevity by promoting a healthier lifestyle and reducing the risk of chronic diseases. Regular exercise supports cardiovascular health, improves muscle strength, and enhances flexibility. Engaging in physical activity also aids weight management and boosts mental well-being, all of which contribute to a longer lifespan. Studies indicate that even moderate levels of physical activity can lead to reduced mortality rates. Moreover, being physically fit often correlates with healthier aging, allowing individuals to maintain independence and quality of life as they age.
