It can be seen from the activity of nerve cells in the brain that the more the brain is used, the more flexible it will be. Simply put, the so-called smart people are those who can use their brains to the maximum extent; On the other hand, a stupid person is a person who is too lazy to think.
However, why is the human brain getting smarter?
Is anyone worried? Excessive brain use? It will damage your health and even shorten your life. In fact, this kind of worry has no scientific basis. On the contrary, people's brains will become more and more flexible. An American scientist pointed out that if an ordinary person can study tirelessly all the time, his brain will store 50 times as much knowledge as the Library of Congress (which has about 200 million books). It can be seen that the human brain's ability to store information is amazing. However, due to various factors, even the person with the best memory did not reach 1% of this memory.
There are about1400 million nerve cells in human cerebral cortex, while the average person only uses about1000 million in his life. In other words, a large part of the human brain's potential has not been exploited. Around the age of 30, brain nerve cells will gradually decrease at a rate of more than 65438+ million per day.
? Use it in and waste it out? The principles of biological science also apply to the human brain. Brain nerve cells, like other tissues and organs, can maintain vigorous vitality when used too much. If you don't use it all the time, the number of nerve cells will decrease faster.
Therefore, if you work hard, your brain will always be young; If you are lazy, you will be slow to respond, and Alzheimer's disease will easily occur in old age. According to the survey data, the intelligence of people who use more brains is generally 50% higher than that of lazy people; Older people with high academic qualifications and high professional intelligence are usually much slower and lighter in brain aging and mental decline than those with less intellectual activities.
