The links between fitness and longevity are well-established, with regular physical activity contributing to a longer, healthier life. Exercise lowers the risk of chronic diseases, including heart disease, diabetes, and certain cancers, while enhancing cardiovascular health. Active individuals typically benefit from improved mental health, including reduced anxiety and depression. Fitness activities, combined with a balanced diet, promote vitality and functional independence as people age. Thus, maintaining a consistent fitness routine can significantly enhance both the quality and longevity of life.
