Why do people get old, and why do people get old?

No, there are too many old people to stand up.

This is in accordance with the law of conservation of energy in physics.

1.This is the law of nature. No one can avoid it. Entering old age also means that you are no longer young. Age, intelligence, and physical condition will change.

2.Overexertion, which leads to a decrease in melanin. The hair turns gray, and the hair is not smooth and delicate. are all signs of aging.

3.Staying up late accelerates ** metabolism and absorption slowly, leading to early entry into old age.

4.Although people get old. are afraid of getting old. But keep a good mood. Good attitude. Always 18 years old.

Hello friend, why do people get old? This is the law of nature, everything is growing, developing, changing, our society is also like this, everyone is changing, as we get older, our body's functional cells will get old, they will age, so we will get old, we have to accept this fact, I hope everyone can treat their lives correctly.

Because of the laws of nature, the laws of nature stipulate what people have to go through, birth, childhood, youth, middle age, old age. This is biologically associated with irreversible aging of cells.

Because birth, old age, sickness and death are natural laws, on the one hand, there are physiological factors, and the other is pathological factors. With age, the human body's physiological and psychological adaptability to the environment will gradually decline, and gradually tend to die, that is, the so-called physiological aging and pathological aging.

This is caused by genes, if in the future human beings can genetically change the law of birth, aging, sickness and death, to achieve a reversal, human beings do not need to get old, but it is not realistic, there is no need to have children, because the population will be more and more.

As you get older, your function will decrease, such as gray hair, joint pain, and physical exhaustion.

In fact, the process of aging is a process of oxidation, with the growth of age, the body's various functions are declining, that is, being oxidized more and more, but this process is irreversible.

Because the metabolic level of a person cannot be kept in a very vigorous state all the time, he will produce a certain amount of consumption after using too much, and he will become old.

Many scientists believe that harmful free radicals accumulate in the human body due to exposure to various rays, the use of chemicals, and excessive iron in food. This free radical is the main culprit that causes the human body to age. The average life expectancy of human beings has only increased from 45 years ago to 74 years more than 2,000 years ago.

By far the only person with the highest human life expectancy was the Englishman Ferm Kahn, who lived 200 years. Scientists point out that the natural lifespan of humans should be 100,150 years.

Anti-aging and anti-aging have always been the goals that human beings have been pursuing in history. In the past, people did not understand the causes of aging and the mechanism of aging, so no matter how many elixirs of immortality there were, they were not credible.

Harmful free radicals accumulate in the human body due to exposure to various rays, the use of chemicals, and excessive iron content in food. This free radical is the main culprit that causes the human body to age.

It's normal for people to get older, because when people get older, their cells get older and older. As long as it is a human being, it is very common to experience birth, old age, sickness and death, and can only accept it calmly, and scientists have not studied the secret of immortality.

Because people have to grow up slowly from a young age, people will grow old, be born, get old, sick and die, which is also something that people should experience in their lives.

It is a natural law of human birth, old age, sickness and death, so the reason why people will grow old is because people have to consume in the process of life, and organs and other organs are aging, so people will change.

People will get old because their organs will age, and people's ** will oxidize.

People grow old, and it's irreversible.

If human cells do not oxidize, then people do not grow old.

Birth, old age, sickness and death, human nature, just like animals and plants, the human body will grow and develop, and then the cells wither and die.

Why do people get old, this is the natural law of life, as we slowly grow older, metabolism emerges in an endless stream, and gradual aging is also a very normal thing.

My view is that people get old. ......When we are young, we pursue happy and sweet love and career success. ......And when we are old, we also pursue a better life, and hope that our old age life is happy and happy every day.

Specifically, our ideal old age should be in the following states:

1. Be healthy, happy and happy every day.

Each of us wants to be healthy, mentally happy, and happy every day.

As we move into old age, we pay special attention to this aspect. ......This is because when we enter old age, our physical condition is not as good as when we were young, so our pursuit of physical health is more ......And when you have a healthy body, you will naturally be happy and happy, and every day will be relaxed and happy.

2. Do what you can and give full play to your spare heat.

When we enter old age, we will retire and rest at home.

However, after retirement, we are not idle ......At this time, what we are pursuing is to do something for the elderly, give full play to their spare energy, and prove that we still have the ability to make new contributions......This kind of old age life will be more meaningful.

3. Enjoy life and make your old age life smooth.

When we get older, we want our lives to go well.

Therefore, at this time, we will pay more attention to the quality of life, pursue the quality of life, let ourselves enjoy life better, and our old age life will be more comfortable and satisfactory.

4. The family is harmonious, the life is comfortable, and the family is happy.

Family happiness and a happy life are the pursuit of each of us.

As we get older, we will have a stronger ...... in this regardWe will pay more attention to the state of family happiness and harmony together, fully enjoy the joy of family, and share a good life with our families.

That's what our ideal middle-aged life looks like ......Because different people have different ideas and different pursuits, the ideal old age life in everyone's mind is different. ......However, everyone has the same ...... when it comes to getting old, enjoying life, and being happyThis is what our ideal senior life should look like.

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. Hope.

Because a person's cells change from childhood to adulthood. As a child cell, he will be. Well, it's smaller, but it will branch, that is, from one cell to two, three, four, five, and gradually more, but some cells will not grow anymore to a certain extent.

Then, as we age, we slowly stop growing cells, and we gradually increase. to a certain age. It depends on how fast or slow your cells are differentiating.

Depending on your height, grow fast or slow. Then if the watermelon no longer grows. And then you will gradually get older.

Aging is a natural law, not only for people, but for everything in the world. Even if you have a good attitude and a healthy body, it only delays aging, and cannot change the reality of aging.

This is a natural phenomenon, a natural law, what should come will come, and what should go will also go! All you can do is live in the moment!

Why do people get older? People go by with the passage of time. With the years of hard work.

People get older. But if people don't have to worry about earning money and doing any work, then they will age more slowly. If the person is very.

It's not easy to worry about anything. Such people who have to go through ups and downs to achieve it will be easy to get old. People are like machines, over time, every part will get old and smelly.
