Everything in nature is a seemingly disordered but orderly process. All things grow to wither, stones weather to powder, and the earth is endless, but in fact everything is changing in an orderly manner.
The same is true for us humans. Since ancient times, kings, princes, generals and ministers have been pursuing the art of immortality. Of course, everyone knows that aging is the law of nature and a fate that no one can escape.

American scientists have measured the life expectancy limit of humans, and can live up to 150 years old
Before , a study published in "Nature Communication" shows that , humans have the chance to live until 120-150 years old!
Researchers believe that the essence of life aging is the decline of self-healing ability. When the self-healing ability is completely lost, that is, when you die, if you want to know how long you can live, you only need to know the critical value of of your self-healing ability .
To explore the ultimate life span of human beings, researchers have established a new indicator - "Dynamic Bacterial Status Index (DOSI)" , which is used to quantify the time it takes for a person to recover from disease.
Through the analysis of the health data of 544,000 participants, the researchers found that DOSI is related to age, lifestyle, and chronic diseases, and the time for human self-repair will be longer as they grow older.
Finally, based on data trends, researchers concluded that the moment when the body's self-resilience reaches the critical value is at some time between 120 and 150 years old, and the life expectancy limit of human beings will be 150 years old.

Why do most people live less than 150 years old?
Nowadays, the average life expectancy in my country is 77.93 years old . Why do most people live less than 150 years old?
1. First of all, a person's life expectancy meets normal distribution . The upper life expectancy limit is originally a special situation and will definitely be greater than the average life expectancy.
2. Secondly, internal factors, including genetic factors, steady-state various material levels, etc.,
3. Finally, environmental factors, including living standards, eating habits, psychological state, etc.
Multiple factors determine that most people cannot live to the limit of their lifespan. In fact, objectively speaking, they are relatively lucky to be able to survive through the average lifespan.
However, as we age, the body's functions gradually decline. At this time, various chronic diseases will gradually come to us, which will reduce the quality of life in our later years.

You are just old, not sick! After the age of 50, if there are these changes in the body, it is normal for
Hand shaking
People will experience hand shaking when they get old, mainly related to insufficient muscle endurance and neurological lesions. As they age, the organ function of the body decreases, the strength of muscle atrophy decreases, and hand shaking is prone to insufficient muscle endurance.
If it is a mid-region neurological lesions, such as Parkinson or primary tremor, it is also prone to hand tremor. If the hand tremor symptoms are obvious but last longer, you can go to the hospital for examination.
Arthropathy
Many elderly friends have knee arthritis, and is actually a degenerative disease of synovial joint . Arthropathy in human body should be considered a typical symptom.
Some even have severe symptoms such as joint hypertrophy and deformation, cartilage wear and degeneration, joint slippage, memitis, etc., which leads to joint stiffness and dysfunction of , which will cause very painful for the elderly, but this condition is an elderly disease and does not require excessive treatment.
Blood pressure rise
If the blood pressure in the body continues to rise, timely intervention is required, otherwise it is easy to affect blood lipids and blood sugar, especially for people around 50 years old, blood pressure should be controlled within a reasonable range.
html After the age of 150, the vascular elasticity of in the body decreases, the contraction ability becomes worse, the blood circulation speed becomes slower, and it is more likely to suffer from hypertension . If your blood pressure does not exceed 150/90, you don’t have to worry too much about . If your body has obvious adverse symptoms, you should intervene in time.
Constipation in the elderly
Constipation in the elderly is a particularly common symptom, especially among the elderly. The main manifestation is the reduction of bowel movements and has difficulty in bowel movements. Some people with more serious may defecate less than twice a week or only once a week.
The organ function of the elderly has undergone physiological decline, and the intestinal peristalsis capacity has decreased, which can easily lead to feces being trapped in the intestines and cannot be excreted.
The rectal muscles and abdominal muscles of the elderly have atrophy. Low muscle tone will lead to weakness in defecation and too fine diet. There is less dietary fiber in the food, which can easily lead to difficulty in defecation.
Hearing and vision decline
As age increases, the human lens and retina will gradually become hard and lose elasticity, resulting in a slow decline in vision, which is prone to blurred vision, dark shadows, etc.
html Between 545 and 55 years old, it is the high age of presbyopia 6. There is no need to over-treat after presbyopia occurs. You just need to go to the hospital to wear the appropriate reading glasses . Be careful not to use your eyes excessively and pay attention to eye hygiene.
Hearing loss is also a very normal manifestation. If you feel that the problem is too serious, you can go to the hospital to wear a suitable hearing aid.
