Sometimes the brain can't turn around and forget things in an instant?

It depends on how old you are. Old people may lose their memories, or they may suffer from mental illness. Young people mean that you are not focused, so you forget a lot of things. Don't pay too much attention to what the old man said. This is a sign that the elderly will come slowly. If it is said by young people, you should pay attention to what the main reason is. This little problem of going to Hohhot has serious consequences. I wish you an early health.
