Wang Jian often puts out some brave words to let human beings live to 120 years old. He even made a tombstone by himself, with a black-and-white photo of him, which read: Wang Jian (1954-2074).
"Whether you are infected with COVID-19, you need to do nucleic acid testing." This is a familiar word recently, and the word nucleic acid appears frequently.
What exactly is nucleic acid? Nucleic acid is a biopolymer and an important part of all known life forms. Nucleic acid is a general term for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Every cell contains nucleic acid, which is a very stable genetic material. Once it changes, it means that the cell division is abnormal and the function changes.
What is a gene? The popular science book says: genes are DNA fragments with genetic information, some of which play a role directly with their own structures, while others participate in regulating the expression of genetic information.
With the improvement of living conditions, human beings have a higher pursuit of their own lives, that is, how to live longer and have more time to enjoy the beauty of life. So what determines our own life span?
After years of research, scientists have found that human health and longevity depend on lifestyle and behavior 60%, genetic factors 15%, social factors 10%, and medical properties 15%. Among them, lifestyle and behavior, that is, self-care, account for the largest proportion, reaching 60%.
On the one hand, genetic factors account for 15%. According to research, there is a close relationship between genes and life span. Everyone's genes are different, so everyone's life span is different. Although genes play a major role in life span, life span is determined by the comprehensive balance of multiple genes. Why do some people live long and some people live short? In fact, apart from congenital inheritance, what is more important is personal living habits.
On the other hand, lifestyle and diet are also crucial, accounting for 60%. Only by ensuring that you have a good living habit and don't stay up late, smoke or drink at ordinary times can you reduce the incidence of various diseases. In addition, it is more helpful for health to do proper exercise to keep the body in motion for a long time.
Bad eating habits have become another hidden danger to modern people's health. Now people often eat some junk food, such as fried food and barbecue food, which contains a lot of carcinogens. Although delicious, it is unhealthy. These foods only provide calories and have little nutrition for the body. On the contrary, they will consume more nutrients such as digestive enzymes.
In addition to the above two factors, medical conditions and natural environment will also change people's life span. In ancient society, the average life expectancy of human beings was only twenty years old. China was only thirty years old before liberation, and now he is over seventy. During this period, it is obvious that people's genes have not changed much, but their living environment has changed. At present, backward and war-torn countries with the shortest life span, such as some countries in Africa, have the longest life span in Japan and Western Europe, while China has the longest life span in Shanghai and Beijing, which proves that social progress and scientific and technological development will promote the continuous growth of human life span. There are many centenarians in Bama County, Guangxi and Nanshan Village, Hainan, and they have the reputation of being the hometown of longevity in the world, which proves that natural environment and eating habits can bring longevity.
Many chronic diseases in modern times are caused by genetic damage. Modern science has proved that if genes are normal and cells are active, people will be healthy; When genes are damaged and cells mutate, people will get sick. Therefore, the human genome contains most of the genetic information of human birth, aging, disease and death. Decoding it will bring a revolution to the diagnosis of diseases, the development of new drugs and the exploration of new treatments.
On June 26th, 2000, Britain, the United States and China announced to the world almost at the same time that they had completed the landmark gene sketch project. Then, the completion of the accurate map of gene sequence has brought unprecedented changes to the prevention, diagnosis and treatment of diseases, making it possible to evaluate the genetic risk of diseases.
In short, your basic life span comes from congenital inheritance and acquired maintenance. It's not impossible to pay attention to health preservation and live for decades. It depends on whether you have the determination to live longer.
