Why do people get old? Why do people grow old?

Just like machines, they age, because our organs age, and perpetual motion machines don't exist, and our bodily functions are depleted all the time.

Why do big trees live so long?

Because its cell turnover rate can reach 80%.

But humans can't.

So we age fast.

We must cherish life even more.

Because everyone only has one life.

The reason why people get older is that as they age, the "garbage" in their blood vessels gradually increases.

These "garbage" are polymerized by cholesterol, triglycerides, free radicals, etc., and these "garbage" will gradually adhere to the inner wall of blood vessels, causing the official lumen of blood vessels to gradually narrow, the elasticity of blood vessels to gradually deteriorate, and blood circulation to gradually deteriorate.

Because blood contains all kinds of nutrients needed by the human body, all parts of the human body need blood nourishment. After the blood circulation gradually deteriorates, all parts of the body will gradually lack nutrients, so all parts of the body will gradually age.

Detailed explanation. Aging is the process of "oxidation" of the human body. 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.

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.

With the change of time, our age is constantly increasing, our appearance, our body will continue to change, people will grow old, children will grow up slowly, this is a process.

If there is birth, there will be death, and if there is no old age, there will be no new life, only new life, and if there is no old age, then there will be more and more people on the earth, and they will not be able to bear it at all.

Why do people grow old? This is in line with the laws of nature, everything has a process of birth, growth, and finally aging and death.

Why people always grow old is the law of nature, the day when everything will go to destruction, what the human brain goes to is just a process of destruction. There is nothing eternal in this world. That's why people will always get old.

This is the law of nature, and people will always grow old. Day by day, day by day. Aging day by day, this is the law of nature, there is no elixir of immortality. There is no immortality.

It's good to go with nature, as long as anything is alive, there will be a process of birth, old age, sickness and death, in fact, if you look at these things, it is natural, so don't have too many worries.

The common feelings of birth, old age, sickness and death, people are naturally getting old is a natural phenomenon that cannot be resisted, so we must have a normal attitude to face it, everyone will be old when you get old, as long as you keep your mentality young and happy to live every day.

The fundamental cause of human aging is apoptosis, and there are many factors in life that lead to apoptosis, such as natural factors, environmental factors, pathological factors, etc.

Birth, old age, sickness and death are an inevitable part of human growth. Because there are a lot of cells, and after a long time of work, they are tired. Well, slowly, you will grow old and weak. I'm sorry.

There are always people who grow old and there are always people who are born, so this is the normal state of life, old age, sickness and death, everyone will grow old and accept new life.

Because life is a process, it is a process from small to large, from large to old. So people always get old.

People's birth, old age, sickness and death are really the norm, the laws of nature, the laws that no one can fail to follow, no matter what, always live well.

The natural phenomenon of birth, old age, and illness is that people are born to face slow aging, and everything in the world is slowly aging, and there is nothing to doubt.

In a person's life, there will always be birth, old age, sickness and death, some are sick, some are outside, and people don't know whether the outside comes first or the disease comes first.

Because birth, old age, sickness and death are also natural phenomena, no one can change them.

Why do people grow old? I think it's the change of time, and the passing of the wheel that no one can stop.

Why do people grow old? That's really the way it is, birth, old age, sickness and death, everyone has to go through.

If everyone weren't old, the earth would be crowded.

Life is short, and when you wake up unconsciously, life is close to evening. How are you doing now? Whether it is a man or a woman, when you look back on your life after entering the 60s, there will always be some familiar relatives, old friends, classmates, childhood playmates, and former colleagues, who have already driven the crane west to enjoy Elysium in heaven, which is also an unavoidable natural law in life.

Cherishing life and cherishing the good life of the present moment is extremely important for all people, whether you are men, women and children, young people, middle-aged and elderly people, or the elderly. People often say to maintain a good attitude, be broad-minded, be kind to others and treat yourself, less to complain, more tolerant and tolerant, and live every day happily.

In real life, there will always be some people who tend to fight for a sentence of language, a trivial matter, and fight for the so-called face, and make themselves extremely unhappy. As a result, depression or resentment accumulates, and tolerance allows you to take a step back and open the sky, which is very easy and easy to say in words, but why does it seem very laborious to do in practice! Maybe it's human instinct!

When a person is getting old, it is like a kitchen knife in life, the knife gradually becomes dull, and the personality and temper will naturally get some changes and adjustments. People often use a ridiculous language to say, "You can't even fart anymore"!

Although it is only a ridiculous language, it illustrates the existence of some facts from one side. What can you do when you are old, no matter how glorious your past history was, and now you are in the queue of old people.

It is a natural law that people will always grow old, and how to adjust one's health and life is also a simple and complex life science. Nowadays, some so-called "rich diseases", such as: heart disease, high blood pressure, diabetes, gout, arthritis, etc., doctors are powerless, just rely on drug control and conditioning, and there is no thorough way.

When people are old, look at everything, don't expect too much, please put health always first, live the moment and cherish every day of your life!
