The connection between fitness and longevity is supported by evidence linking regular physical activity to increased lifespan and reduced risk of chronic diseases. Engaging in exercise helps maintain a healthy weight, improves cardiovascular health, and enhances muscle strength. Studies show that those who remain active throughout their lives often enjoy better mobility and quality of life as they age. Furthermore, fitness positively impacts mental health, contributing to emotional resilience and social engagement, ultimately fostering a longer and healthier life.
