There are many factors that affect aging, which can be roughly divided into internal and external factors, the external factors are mainly environmental factors, and environmental factors have two kinds of internal environment and external environment: heredity and aging: this leads to early and late aging, and short and long lifespans.
According to some statistics, at least half of the long-lived elderly have some of the compatibility of the previous generations of long-lived people. Generally speaking, the telomeres of its chromosomes are long, and they have a long lifespan. It is also possible that there are aging genes in people, that is, the "biological clock", and aging is the process of accumulation of these degenerative properties.

The external environment includes climate (temperature, humidity, solar exposure), soil and water quality, sea level, environmental pollution and ionizing radiation, anions, etc., which may affect the aging of the human body. Certain environmental pollution, such as urban pollution and smoking pollution, can cause people to grow old age.
The biological environment, such as various pathogenic microorganisms, is also one of the reasons for this. The internal environment refers to the gradual deterioration of the functions of various organ systems in the human body.

Specifically, before we want to get some answers from the mechanism, we must first understand that the basic building blocks of the human body, cells, tissues and organs are similar to a chain structure, and the wear and tear of cells can lead to a series of damage. The body accumulates a large amount of waste products in the process of cellular metabolism, and the accumulation of a large number of waste products will lead to melasma or freckles in people, which is the result of the accumulation of waste products in ** and internal organs.

Aging is a problem that everyone has to face, even if today's medical aesthetic technology is developed, it is beyond the reach of one day, because aging can be alleviated and irreversible, only through healthy means to alleviate and delay aging. The aging of the human body is the aging of blood vessels, and it is the gradual disappearance of capillaries.

According to some statistics, the number of cells in 60-year-olds is 70% that of young people, and the activity of B cells to make antibodies is also reduced, so that the antibodies in the blood are reduced, and the content of thymosin in the blood is also reduced, so the immunity is reduced, so it is susceptible to infection. Endocrine includes the senescence changes of the gonads, thymus, thyroid, adrenal cortex, pituitary gland, etc., which cause the physiological functions regulated by them, thereby causing the aging of the corresponding body.

A person's body is aging again, because it will continue to move forward with time, and its cells will also become old.
-
After all, the amount of water and collagen in people's bodies is getting less and less as they age, so they don't age.

Generally speaking, as the body hardens with age, the range of motion of the joints becomes narrow, the muscle mass decreases, and the tendons and ligaments also become hardened. Moreover, people who are often endowed with a sense of humor and a flexible brain will also have a soft body; And people who are very strict and rigid in their thinking will have a stiff body.

How does aging occur? Each sect has its own interpretation. Roughly speaking:
Our body is supposed to be a well-functioning machine (although it is a bit inappropriate to compare the human body composed of living things to a machine, but this is the most apt analogy that Uncle can think of), but this machine has an expiration date. Once the service is overdue or the maintenance is not done properly, the parts in the machine that originally fit well with each other will bump into each other due to wear and tear, further accelerating the damage rate of the parts.

1. If an unexpected and serious illness occurs day and night, and you can't take care of yourself, watching your children contribute money or effort is far more sad than your own money or effort.
If you don't have much savings or no pension, it will undoubtedly be worse for your later years, and you will have to reach out to your children. Parents will pay for their children when they are young, and when they are old, they still want to reduce the burden on their children by taking good care of their bodies or being financially self-sufficient.
When you can't help your children, you will create a burden on your children, and even if your filial children work hard, parents will feel uncomfortable in their hearts. Although the children of parents have countless selfless dedication, when it is the turn of the children to pay for their parents, the small contribution will make the parents happy, and the big contribution will make the parents unhappy.
Second, when people reach old age, the greatest sorrow is that the wife goes first, and the other half who stays in the world will be in a dilemma, whether it is to find a wife again or to be widowed, it is an extremely difficult road to take.
Sometimes the greatest sorrow is followed by greater sorrow, such as when the house leaks, it happens to catch up with the overnight rain. The exclusive overnight rain in later years means that the children are not filial, and there are many precedents for the elderly who are abandoned by their unfilial children, and the precedents of the elderly who are disliked by their unfilial children are often heard and witnessed. In addition to the lack of family affection, the lack of friendship can still be regarded as sad, without one or two confidants or three or five friends, even if you are not ruthlessly abandoned by the society, you will feel ruthlessly abandoned by the society.
Third, the lack of hobbies often leads to idleness at home, and no favorite hobbies will experience living like a year, and every day will be tormented, not only to eat and mix with dark, but also to eat and die.
If there is no hobby at home, and there is no interest outside the home, the old age will lack the necessary vitality, until pessimism replaces optimism, and the old age is not the sunset, but the twilight. Whether you will feel sad in the second half of your life is not up to others, but to yourself. You have the final say, and if you can do what you say, you can control your destiny.
Conclusion: Be prescient when old age has not yet come, and wait until the old age comes, if it is ongoing, and strive to deal with it wisely on the basis of calm response.
