Of course, it is good to keep exercising. The correct exercise method can not only prolong life, but also keep the body light and not easy to get sick. Even at a very old age, an old man can have a tough physical condition by keeping fit. Whether a person can live a long life depends on his physical condition in his later years. Good health and a good appetite will naturally lead to a long life. If you are in poor health, people will have various diseases when they get old, and naturally it is difficult to live long. Besides exercise, it is also important to pay attention to diet. Eating habits and rest habits are well done, and the endocrine state of the body can be well regulated. If you have bad habits, don't take part in sports, and eat irregularly, even young people will become haggard and have unhealthy symptoms such as hair loss, osteoporosis, headache and qi deficiency. And irregular diet will seriously damage gastrointestinal health. If you have a bad stomach and a bad appetite, you can't digest and absorb it well. If you can't eat, your body will naturally disappear, let alone live a long life. And the symptoms of obesity caused by overeating are also the enemy of longevity. In fact, in this way, it is better to say that people can live to their healthy age than to achieve the goal of longevity through exercise and healthy eating. Our life span actually depends on the length of telomerase in genes and chromosomes. Many able-bodied old people die naturally at the age of 80, 90 or even 100, which is called natural death. No matter how long you live, you can't get rid of the rules of life, so no matter how you exercise, you still have to go when it's time to go. However, adhering to correct living habits and taking good care of your health can at least make you live comfortably to that age, close your eyes and go to sleep peacefully and leave this world, instead of dying painfully in a hospital bed early because of various physical diseases.
