The old is not compiled by Zhang Baotong

Humans have always dreamed of immortality, and now, scientists are learning more and more about the aging of the human body and why it is ageing. This makes the dream of human immortality closer and closer to reality. So, what will happen when human lifespan is truly extended?

In the past, many people thought that diseases were caused by aging, but studies have shown that many diseases of old age are only related to poor diet and hygiene, and have nothing to do with aging. Even those old age phenomena such as gray hair, slow reactions, hearing failure, and decreased cardiopulmonary function are actually not related to age.

Studies have shown that there are two particularly effective ways to curb human aging: 1) physical activity and a sensible diet, and 2) injecting natural hormones into the body. Physical activity with a sensible diet is by far the most effective and widespread method. Dr. Browders, a doctor in Maryland, requires his patients to eat low-fat, low-cholesterol foods and be physically active. The effect is very noticeable. One-third of his patients live beyond 80 years, with the largest as high as 103 years old. Fifteen years ago, we thought that aging was a natural disease that could not be helped, but now that people know the causes of aging, they have begun to change their habits of smoking, drinking and other bad habits, realized the importance of exercise, and gradually corrected some behaviors that lead to aging.

Another way to curb the aging of the human body and maintain human health is to inject natural hormones into the body. Such hormones include pituitary preparations for the adrenal, thymus and thyroid glands. The natural flow of these natural hormones in the body is regulated and directed by the hypothalamus and brain clock. When a person is 25 to 30 years old, the concentration of these hormones in the human body peaks, and by the age of 80. These hormone concentrations are reduced by 95 to 100 percent. Dr. Radman of Idnos said, "The decrease in these hormones is what makes the elderly obese. If the body no longer produces these hormones, the elderly become weak. In 1989, Dr. Radman conducted an ornamental trial in Wisconsin for a Chicago veterans' nursing home. This reality reverses the process of human aging. He injected heart hormones into 27 elderly men every week. The old men suddenly looked much younger, fat and thin, weak and strong. One elderly person said, "I've never felt this strong in my life." I felt like I had rejuvenated. Not knowing what side effects this real yàn would have, Dr. Radman stopped real yàn after a year. These signs of rejuvenation disappeared with it. There are also researchers who are using gene therapy to do this. This kind of real yàn is to normalize genes that effectively limit physiological lifespan. They are also trying to develop an artificial growth hormone. This hormone works in the body, restoring the body's muscle mass, smoothing the skin, and improving the body's body and energy.

If a person's life span can be extended by 30-40 years, he will replan his life. Perhaps when he enters middle age, his family is more stable, and his economy is relatively wealthy, he will relax and go back to school to learn a subject he really likes. Many scientists believe that this cyclical lifestyle pattern will be an inevitable trend in the society of the coming wave of old people.

The extension of human life will inevitably affect their understanding of friendship and love in life. In the last 15 years, one out of every two couples has divorced. Moreover, the divorce rate of the elderly over 60 is rising sharply. If a person feels that his marriage is not happy at the age of 60, and he only has a maximum of 5 years to live, he will say, "Forget it, make do with it." But when he is confident that he will live to be between 90 and 109 years old, then he is likely to dissolve his marriage and find a happy marriage. At that time, it will be very common for gray-haired people to chat, fall in love and form a family together. In fact, it is now in the newspapers that you can see the elderly matchmaking every day. At the same time, in the process of finding happiness for themselves in their old age, the elderly will also do their part for the society and create a welfare.

Dressed in a thick sweater and leather jacket, I walked on the hillside in the afternoon against the bitter north wind. Snowflakes fell silently on the wild cherry trees. The cold wind blows up snowflakes, and the bare frozen ground is like rocks. The earth fell silent in the cold winter day, and the earth seemed to have lost its life. Yet, like a child, every field and hill in the north contains the vigor of the seed of life. Whether it's insect eggs or thorn fruits, the birth of life has always been sleeping and waiting in winter.

At this time, the earth is covered with rhizomes and seeds, winter buds bloom on the branches of ****, live pupae of turtles, frogs and dragonflies hide in the frozen soil, and fertilized queen wasps and wild queens hibernate in the rotten trees and under the rubble of the eaves. In the cold around us, although life has been temporarily suppressed, life has not been suffocated, just a nap, waiting for the arrival of spring. Only in this way will the summer flowers bloom, the thousand leaves will shine, the grass will be green, and the midsummer night will exude a refreshing fragrance. And in the golden light of August, dragonflies flutter their wings and sparkle. Now, these innate instincts are locked up in the earth.

This temporary hibernation is not time-consuming. Scientists have found that many seeds have to go through months of cold, just as they do in the spring. Under the snow and ice, the seeds lie in the frozen soil, but they can receive the most blessings. If these seeds are brought indoors, cared for, and kept warm from the cold and wind, snow and cold, they will not germinate vigorously in early spring. In this way, the harshness of this winter is a priceless boon. Because the eggs of some insects also need to go through a cold before they can hatch.

Severe winters can be described as a natural disaster for fragile lives, but not for all lives. It is conducive to the normal growth of seeds and eggs. On a harsh winter day, the sky is cold and the earth is as silent as if it is dead, which is actually an illusion and an illusion. Life is everywhere, in every inch of frozen ground, in every inch of rocky solid soil. The natural forms of life are vivid and mysterious, and endless.
