Abnormal performance 1: recall the past and sum up your life. When old people suddenly like to recall the past with their children, they often recall what they did when they were young. What is happy for you and what is painful for you are all clear-headed, especially when you were a child's playmates, who are more and more serious about the idea of growing up.
Abnormal performance 2. Often dreaming Some old people are bedridden, but they often dream, and dreams are related to their own bodies. He often talks to you about how good he was when he was young and how hard he worked. How hard I work, I am always reluctant to part with my past body, and I am puzzled by being bedridden now. I always make some excuses for myself, thinking it is a minor illness.
Abnormal performance 4. Explain the aftermath, just like making a will. If the old man at home suddenly chats with you about the world, it implies that the old man may be dying. Many old people can detect the changes in their bodies and feel that they are dying.
