The ancients said that life is rare for seventy years. It means that since ancient times, people at the age of seventy have never been rare, and in the eyes of the ancients, the age of seventy is already the limit of longevity.
The reason why the ancients expressed such feelings was because in that era, the standard of living was very poor, and it was difficult to solve even the most basic problems of food and clothing, and the medical level was very poor, and they may have had an ordinary pneumonia, because they could not get timely treatment, and they could also die because of it.
Now it is completely different, people live in a peaceful era, no longer worry about food and clothing, and the level of medical care is very high, some diseases used to be terminal, but now they can be completely cured, such as tuberculosis and so on.
Although there are some diseases that cannot be cured, such as coronary heart disease, hypertension, diabetes, chronic obstructive pulmonary disease, etc., these diseases can be stabilized through scientific treatment.
Some elderly people, even if they suffer from multiple chronic diseases, can live with the disease for a long time.
Therefore, now the average life expectancy of people has easily exceeded 70 years old, however, to measure longevity, not only by age, the same is 70 years old, some old people are still hard, but some old people have been paralyzed in bed, life can not take care of themselves, which old man has a longer life, the answer is clear at a glance.
Therefore, even if the current standard of living and medical care has improved, it is still necessary to pay attention to the age of 70, the reason is very simple, at the age of 50 or 60, many old people may not feel significantly old, but at the age of 70, it is completely different.
In a new study published in the authoritative journal Nature in 2022, a research team led by the University of Cambridge followed 10 newborns for 81 years to analyze the changes in bone marrow blood cells in the body from the neonatal stage to the age of 81. Research has found a process that prompts "catastrophic" changes in blood composition in older adults, explaining why people suddenly become frail and old when they reach their 70s.
The results showed that after the age of 70, the population structure and differentiation pattern of human hematopoietic stem cells changed dramatically.
Researchers say that people gradually accumulate mutations throughout their lives, and the changes in the number of blood cells in old age explain why the body suddenly becomes fragile after the age of 70, and people also have a significant sense of aging, and the diseases caused by aging will also increase significantly.
Therefore, at the age of 70, many elderly people tend to experience cliff-like aging.
70 years old is known as the life span of the elderly, only through the 70 years old, in order to better sprint towards the age of eighty or ninety, 70 years old, the elderly to do five things.
1. At the age of 70, the elderly must go to the hospital for regular physical examinations

2. At the age of 70, the elderly must pay attention to maintaining balanced nutrition
The elderly should pay attention to the balance of nutrition, not only to supplement foods rich in high-quality protein, but also to supplement foods rich in vitamins, trace elements and dietary fiber, only in this way can the body's immunity be maintained at an optimal level.
3. At the age of 70, the mentality of the elderly must be put in place
Birth, old age, sickness and death are natural laws, do not worry too much, the mentality should be put in place, and the elderly should keep in mind that only by maintaining a healthy and positive mood can their immunity be in an optimal state.
4. At the age of 70, the elderly must insist on exercising
Life lies in sports, and the elderly who love sports are more likely to live longer.
5. When you reach the age of 70, you must quit smoking and drinking
Many elderly people have the habit of smoking and drinking when they are young, and when they reach the age of 70, they must quit no matter what, otherwise, the risk of disease will be greatly increased, and the quality of life will be greatly reduced.
