The greatest indicator of lifespan is lung size and lung health. There was a study that looked at people for over 52 years and they found that the people who lived the longest had the healthiest lung function. Those who were given larger lungs lived longer than those with smaller lungs. We don't have to get any transplants - we can practice healthy breathing, exercise and lung exercises. #lunghealth #healthylungs #longevity #health #lungfunction #exercise #breathingexercises #healthybreathing #healthtok
