1. The necessity of using the brain frequently lies in exercise, but also in brain movement. Diligent use of brain means constant use of brain, and scientific use of brain is the most effective way to ensure brain function and delay brain aging.
Physiologists believe that the human brain is "put into use and abandoned". If it is used more, it will develop well and prevent "disuse atrophy". The research of American neurobiologists shows that the more brains are used, the longer the dendrites on nerve cells are, and the more information nerve cells receive. On the contrary, if you are lazy, the dendrites will slowly shrink.
British neurophysiologists have found that the cerebral vessels of people who are diligent in thinking are often in a state of stretching, which is conducive to the good maintenance of the cranial nerves and the brain will not age prematurely. Japanese physiologists have observed through experiments that people who have been engaged in mental work for a long time are still very agile at the age of 60, while those who don't use their brains often feel that their memory is obviously reduced and their thinking becomes dull at the age of 30 or older. Yan Jici, a famous scientist in China, famously said, "Keep thinking, keep thinking", and he practiced this sentence. Therefore, he not only made many scientific achievements, but also kept a clear head, quick thinking and intelligence even after he was over eighty.
In order to get data on brain use and health, American scientists did an experiment. 73 elderly people with an average age of 8 1 year were divided into two groups, one group was diligent in thinking and the other group was slow in thinking. Three years later, I found that people who are diligent in thinking group have reached the best indexes in blood pressure, memory and physiological function, and they are all alive in the second month. The mortality rate of mental retardation was 12.7%. For the study of brain use and life span, some foreign scholars selected 400 outstanding figures in Europe and America, and made statistics according to different occupations, and found that scientists, inventors and writers who often use their brains have the longest life span. According to the usual explanation, the memory and intelligence of human brain begin to decline after 50 years old. So some old people are not enterprising and lazy to use their brains, but they don't know that this is extremely unfavorable to the health care and development of the brain. In recent years, scientists in the United States and Sweden have discovered for the first time that even when people reach their sixties and seventies, new cells will still grow in their brains. They found newborn neurons in the hippocampus of some elderly people, which can restore some functions of the brain, which is very important for people's learning and memory ability. This discovery denies the previous scientific conclusion that adult brain cells cannot regenerate after injury, which not only provides a theoretical basis for the treatment and rehabilitation of brain diseases and brain injuries, but also encourages the elderly to re-study and use the brain.
Dr. John Moses, who is engaged in geriatric research in the United States, said: "Learning is an activity involving the whole body, especially the vision, hearing and other senses, as well as the reflection and what we call intention. In my opinion, whether young or old, usually learning requirements will make people healthy. " Examples at home and abroad have proved that the elderly who insist on intellectual exercise and use their brains frequently can keep their brains healthy in any way.
3. The method of diligent use of the brain ① Develop a good habit of reading and studying from an early age and stick to it for life. You should also think more and ask more questions when reading and studying.
(2) To develop the habit of writing frequently, you should often write some comments and argumentative papers, keep a diary, or write manuscripts and works.
(3) Read some relevant newspapers and magazines frequently.
④ Watch TV and listen to radio selectively, and watch or listen to positive programs that can mobilize your mind.
⑤ Develop the habit of thinking more and independently, and be able to put forward or express your own opinions or opinions.
⑥ Attend more academic seminars.
All landowners often accept new education and absorb new knowledge.
