Why do people grow old at a certain time?

Who said that people don't look good when they're old, and they are old and beautiful. If people don't get old, then what is the meaning of life, birth, old age, sickness and death are necessary. If people don't get old, there will only be countless days and years after years, because there are so many tomorrows that there is no end, do you think there will be people working hard in this way?

Life is an accident Death is an inevitability! The process of living is life! Don't ask yourself to take every step is right, just ask yourself to take every step is no regrets, life is enough!

Find the value of your existence while you are alive! Make your life a little fuller!Since you have come to this world once, you can live with him once!

To live, you must have your own "goals" and "dreams", and paint a few colors on your life! If you can't find the value of your own existence, just think about yourself, give yourself an explanation, give your parents, friends, and the one you love the most! Then enjoy the beauty of the sunset, giggle and draw a perfect picture of your life...

If people are not old and the most terrible, you should have seen the story told in "Myth" starring Jackie Chan and Kim Hee-sun. Can you understand why Kim Hee-sun would rather die than go out in the end? If you really don't get old, the most painful thing in the world is to watch your loved ones grow old and die one by one in front of you.

If all people don't get old, the same thing in the world may be to be scrambled alive.

The foundation of traditional Chinese medicine, as stated in the Five Fortunes and Six Qi, is that all things in heaven and earth are born and die. There is a process of growth and collection. Man was born in heaven and earth.

What is not born and does not perish, it will not grow old. It won't get old and it won't cause any problems. Or it exists in the universe in another form, such as sand and microns, and it will not easily cover the world.

The old ones are good-looking, and the old ones are even more beautiful.

This is because of the laws of nature, people don't grow old, isn't the world full of people, the so-called old doesn't go, and the new doesn't come?

Individual functions are declining, and organs are aging.

Aging in human biology is an inevitable process. Both physical and physical functions deteriorate over time, resulting in a loss of physical and mental function that is as strong and flexible as it was when they were younger. Some common signs of aging include sagging, hair loss, memory loss, decreased physical performance, and failure of the immune system and self-repair mechanisms.

Although aging is an inevitable process, studies have shown that people can slow it down through exercise, diet, social participation, health care, and more. In addition, the development of science and technology is also gradually providing new technologies and new drugs to improve aging-related diseases and delay the aging process.

People always want to delay aging because aging brings us many problems and challenges, such as physical and cognitive weakening, susceptibility to diseases, economic pressure and social loneliness. If we can slow down aging, we will have more time to do what we want to do, enjoy life better, and contribute more to society and our families.

In conclusion, although aging is inevitable, we can slow down the aging process through daily life and technological advancements. Maintaining a healthy lifestyle and active social engagement can help us delay the decline of our physical and cognitive abilities, while we can also find new scientific techniques and ways to deal with the challenges of aging.

Typing is not easy, hope.

Life is always old, this is the law of nature. When people reach old age, they are the most harmful.

What I fear is loneliness and loneliness, and what I need most is the understanding, comfort and understanding of my children.

Stick. Respect for the elderly is a traditional virtue of the Chinese nation, and nowadays, some people do this.

The consciousness of respecting the elderly has been weakened, and the phenomenon of gnawing at the old has occurred from time to time. Some borrow weekends.

I went to visit my father and mother, ate and lived in the old man's house, and the old man was busy. Old man, day.

Before dawn, I had to go to Tizhu to buy vegetables, and then I kept cooking and cooking, everything.

Cook the dishes, set the table, and respectfully invite the grandchildren and grandchildren to the table. I have to be busy after dinner.

Clean up the leftovers, clean the cups, plates, dishes, and ......And the children wiped their mouths and went back.

Take a break, pack up the extra food and sometimes leave the child behind for the parents.

Adults take care of it, and retirement at home is really more tiring than going to work.

Pity the hearts of the parents under the Tiandou chain. Today, quite a few people in their sixties and seventies, still.

I have to buy groceries, cook, do laundry, sweep the floor, and pick up and drop off grandchildren for a large family.

Learn. When you are a child, you may wish to empathize, if you are old, your children are right.

How do you feel about you?

As parents, I don't have too high requirements for you, I just want you to take your father.

The mother should just treat it as her own child. This is also the highest courtesy to parents, and it is also the most filial piety. I often hear some old people say, "Children can have something to their parents."

One percent of a child's filial piety is done. It is also said that in real life, some children regard their children as the pearl of their palms, obedient and caring.

stickers, everywhere, but for parents, it's the opposite. There's an old saying.

Good: "The country is upright and the people are happy, the officials are clean and the people are safe, the wives and husbands are less troubled, and the sons are filial to their fathers."

Wide. "However, there are many infatuated parents in ancient times, and they are filial to their children and grandchildren.

People will always grow old and die This is the law of nature I give you advice, do you think it's okay? 1.Look at the world with another eye, not everyone in this world is very smooth, just look at how you solve it, for example, you were hit by someone when you were walking, others apologized to you, sometimes you still feel very angry, but you didn't expect that the person who hit you was actually more uncomfortable than you, or think about the sentence "Happy is also a day, unhappy is also a day, why not be happy every day".

2.If you think that you are in a bad mood, you will be in a bad mood, then you don't need to think about it, if you still want to, then keep yourself busy, let yourself have no time to think about it, let yourself live every minute to the fullest, and then don't fall in love with the bed after waking up in the morning, get up when you wake up, get busy, open the window, breathe in the fresh morning air, relax your whole body, and let yourself imagine a happy little angel ...... 3.Choose a place with fresh air, quiet surroundings, soft light, undisturbed and free movement, and take a position that you feel comfortable in, standing, sitting or lying down.

4.Move some large joints and muscles of the body, the speed should be even and slow when doing it, and the action does not need to have a certain format, as long as you feel the joints let go and the muscles relax. 5.

Take a deep breath, inhale slowly and exhale slowly, saying "relax" in your mind whenever you exhale. 6.Focus your attention on some everyday objects.

For example, look at a flower, a little candlelight, or anything soft and beautiful, and look closely at its subtleties. Light some spices and inhale the aroma of it. 7.

Close your eyes and try to imagine some tranquil and beautiful scenes, such as blue waters, golden sandy beaches, white clouds, mountains and water. 8.Do activities that you enjoy that have nothing to do with the specific things at hand.

For example, swimming, taking a hot bath, shopping, listening, watching TV, etc. 9.Life is easy, life is easy, life is not easy.

Don't worry, there are a lot of people in this society who are almost like you, but they are all living happily, not everyone can succeed, as long as you work hard to treat everything, take life seriously, as long as you take every day seriously, but how your life is, I believe it is wonderful. Go for it! It's hard to live because society is very unfair, it's very helpless to live Sad and sad to cry, find something to do, it's not boring Because life is like this No one's life is smooth sailing When you encounter anything, be optimistic Keep a normal heart.

Why do people get old? To put it simply, aging is the process of "oxidation" of the human body. To give an easy-to-understand example, it is like iron rusting, which is originally smooth and strong, but when it reacts with oxygen in the air for a long time, it oxidizes to form rusty iron.

Oxidation will destroy the original structure of the object and deteriorate, and the oxidation reaction is very slow, such as human aging; There are also very rapid and intense, such as the burning of objects, which is another oxidation phenomenon in which substances have a fierce chemical reaction with oxygen.

Oxygen is not only a gas that humans must breathe every day, but every cell in the body needs oxygen to survive all the time. So why is "aging" a reaction of gasification? To put it simply, oxygen in the human body can actually be divided into "aerobic" and "bad oxygen".

"Aerobic" is generally called oxygen molecule, which is to provide oxygen needed for human cells and physiological activities, and around this "aerobic" molecule is surrounded by pairs of electrons, as if everything is more stable in pairs. However, due to external factors such as environmental pollution, radiation or trauma, the so-called "bad oxygen" is produced in nature and in the body. "Bad oxygen" carries one or more unpaired electrons and is therefore extremely unstable.

Unstable bad oxygen also reacts with other atoms or molecules that are otherwise stable, and as a result, many chemical structures that are otherwise stable become unstable. It's like saying that someone who is short of money steals your money, and then you steal someone else's money because of lack of money, and as a result, the person you stole money from is also short of money and steals other people's money, and a chaotic chain reaction occurs. The "money" in this metaphor is "electrons", and the people who lack money are "bad oxygen" and the chemical structure with one or more unpaired electrons, which is the most popular term "free radical" in modern epidemiology.

However, "bad oxygen" is not really "bad", if it is enough to destroy foreign substances in the human body or resist microbial damage, sometimes its production is also necessary, which is why people will have a lot of free radicals in the body when they are sick or injured.

Everything in nature, whether alive or dead, has a lifespan.

People don't grow old and don't die. That's the supernatural.

That's not normal.

Metabolism caused by oxidative reactions of substances in the body.

Some scientists believe that the accumulation of mitochondrial genetic variation is one of the causes of human aging. Taka Ozawa, a professor at Nagoya University in Japan, and Ansoni Linen, a professor at Monaxiu University in Australia, have found out that the mitochondria, which provide energy to cells, are prone to mutations, and the accumulation of variations is likely to be one of the causes of aging. When the team studied yeast, they found that the sudden mutation rate of genes inherited in the nucleus was one in 10 million cells.

The sudden mutation rate of mitochondrial genes is as high as 1 in 10,000 cells. The team also found that some of the unexplained hypertrophic cardiomyopathy and muscular dystrophy are likely due to sudden mutations in mitochondrial genes. Some scientists believe that the key steps of human aging occur in the brain, but the Institute of Animal Evolutionary Morphology and Ecology of the Academy of Sciences of the former Soviet Union confirmed the theory that the brain has a direct impact on the body's physiological processes by experimenting with mice.

In addition, it was also found in experiments that the growth of transplanted nerve cells was accelerated. The above experiments show that the function of the immune system is directly dependent on the brain. It is hypothesized that it is possible for a person to learn to purposefully control his health and even strengthen his will.

To this end, the institute pointed out that if a person can live to about 200 years from a genetic point of view, this age limit can be postponed by at least 100 years to 300 years with a less complicated operation on the human brain.

Aging is a natural process, which has been systematically elaborated by the theory of natural cross-linking of biomolecules. In demonstrating the molecular mechanism of aging in living organisms, the theory points out that living organisms are unstable chemical systems and belong to dissipative structures.

The various biomolecules in the system have a large number of active groups, and they must interact with each other and undergo chemical reactions, so that the biomolecules are slowly cross-linked to the stability of chemical activity.

With the passage of time, the degree of cross-linking increases, the active groups of biomolecules continue to decrease, and the original molecular structure gradually changes, and the accumulation of these changes will cause the phenomenon of aging in biological tissues. On the one hand, these changes in biomolecules or genes will show different activities or even completely altered gene products, and on the other hand, they will also interfere with the recognition and binding of RNA polymerase, thereby affecting the transcriptional activity, showing that the transcriptional activity of genes is gradually lost in an orderly manner, promoting progressive and regular phenotypic changes and even aging and death in cells and tissues.

Biologically speaking, aging is a spontaneous and inevitable process of living things over time, and it is a complex natural phenomenon that manifests itself in structural and functional decline, as well as decreased adaptability and resistance. In physiology, aging is seen as an ontogenetic history that begins with the fertilized egg and continues to old age. Pathologically, aging is the result of stress and strain, injury and infection, a weakened immune response, nutritional deficiencies, metabolic disorders, and the accumulation of negligence and abuse.
