When p is born, the number of brain cells has been stereotyped. From birth to death, brain cells have been decreasing gradually. One death is less than one. It belongs to non renewable resources. After 20 years old, brain cell death rate quickening, memory becomes worse and worse. Compared with 40 year old people, 80 year old brain cells are less than half, which has been confirmed by science.

< p > memory is not as good as it used to be. This is due to insufficient activity, poor circulation of blood and insufficient blood supply to the brain. This article recommends several ways to improve memory: < /p >

< p > 3. inadvertently stretching is also good for the brain.

< /p >

< p > when the body is in a posture for a long time, the blood vessels of the upper extremity muscle tissue will accumulate a lot of blood. The process of stretching is just the process of muscle tightening and relaxation. The blood is pumped back to the heart, the blood from the heart is much more, and the blood pported to all parts of the body is much more, and the brain can also get a slice of the soup.

< p > 4. good head blood circulation (circulation) function helps to improve memory and delay brain aging.

Carrying a horn comb or finger comb can improve the blood circulation of scalp.

The specific method is ten hands and three or four fingers. From past to later, from top to bottom, combing hair, doing three or four times a day and doing 35 minutes at a time can play an important role in improving intelligence, nourishing the mind and strengthening the brain.

< p > 6. some people say that fingers are the second brains of human beings. Fingers and brains are the most connected nerves. By moving fingers, the brain can effectively stimulate the brain and delay the time of brain cell death.
