Physiological research has proved that more than 95% of information entering the brain is excluded from the cerebral cortex and does not enter the field of consciousness; What really enters the memory bank can be said to be very small. However, it is precisely because of this that what should be remembered can be guaranteed.
Forgetting can reduce the burden on the brain and reduce the consumption of brain tissue. Under normal circumstances, about 65438+ ten thousand brain cells die every day. However, under the stimulation of strong external conditions, the number of nerve cells that die every day in the brain is 10 times that of normal. If this stimulation continues, the brain can't bear it. In fact, with the passage of time, most people can reduce and eliminate this kind of stimulation, which is "forgetting" at work. Sometimes, in order to alleviate some comrades' ideological pain caused by certain things and accidents, we often take the method of comforting or distracting their attention, that is, consciously using the law of "forgetting" to serve the health of the brain.
It can be seen that "forgetting" also plays a very important role in people's ideological activities and can also play a positive role. Therefore, it is necessary for us to master the law of forgetting: firmly remember what should be remembered; If you don't need to remember, forget it quickly. This is also one of the effective ways to promote health and prevent aging (especially to prevent brain aging).
