The connection between physical fitness and life expectancy is well-documented; consistent exercise promotes cardiovascular health, reduces the risk of chronic diseases, and enhances overall well-being. Improved fitness levels contribute to better mobility and functionality as individuals age, leading to a higher quality of life. Engaging in regular physical activity helps maintain healthy body weight and encourages better metabolic function, both critical for longevity. Thus, prioritizing fitness is a vital component for increasing life expectancy.
