The old man lives like a joke.

As the saying goes, there is a family. If there is treasure, don't worry. It happens when we are old. The reason why old people are like old children is that with the growth of age, various functions of the human body will decline to varying degrees, and the mind will be ignored, but this does not mean that the more you live, the more you go back, but because the memory and language ability of the old people will deteriorate in many aspects, and the overall performance is mental decline, which is severe Alzheimer's disease. At that time, no matter how to talk to the old people and explain, the old people will not respond, so be sure to wake up while the old people are awake.
