Why do old people nag?

In daily life, it is quite common for the elderly to nag. The main reasons are: (1) regression psychology. Old people are deeply worried about their past bumpy experiences or mental trauma, or often tell others endlessly, or silently indulge in past sadness. This phenomenon is called "regression psychology" in psychology. The reason why the elderly have "regression psychology" is mainly because the body is gradually aging, and the short-term memory ability of the brain is weakened, but the long-term memory ability is enhanced. Therefore, when something goes wrong, just "touch the scene" and talk about it. In addition, some elderly people lack mental health knowledge, have poor self-guidance and self-liberation, and are prone to "regression psychology". The "regression psychology" of the elderly belongs to a bad psychological mechanism, which will seriously affect their physical and mental health. (2) psychological defense. After children become independent, many things are often decided by themselves and they no longer obey their parents. The instinctive psychological defense function will make the elderly stick to their own opinions and habits, and they will naturally nag when they disagree with the opinions and opinions of the younger generation. (3) excessive worry.
