1, slow heart rate
If a person's heart rate is fast, the burden on the heart will be heavy, and more blood and energy will be consumed. On the contrary, a slow heart rate can ensure the normal contraction and relaxation activities required by the human body, and meet the basic blood circulation needs of human blood vessels in a timely and long-term stable manner. A person's slow heart rate is directly proportional to his life span.
2. Large lung capacity
When young people experience it, they often measure their vital capacity. People with large lung capacity will have very healthy lungs, indicating that they are more capable of inhaling oxygen and discharging waste gas. On the contrary, the decline of vital capacity often indicates that lung function is not perfect, which will lead to more lung diseases. Many long-lived old people have young people's vital capacity, which shows that they are in good health.
3. Strong hand grip
Grip strength is determined by the degree of development of forearm flexors, which can reflect the strength of the whole body from one side, especially for middle-aged and elderly people, and can see the degree of aging changes of the body. Because with the growth of age, the body's muscle mass will gradually decrease, leading to weakened strength, poor mobility, easy fatigue, falls, fractures, slow metabolism and other symptoms.
These are the characteristics of people who live long. If not, we should consciously pay attention to daily health care and at the same time, we must get rid of bad lifestyles.
