Not everyone is selfish, but the degree of selfishness is different and the methods are different. Selfishness is human nature and has a lot to do with personality. Good or bad personality will affect health and longevity. The more selfish a person is, it should be a shortcoming of human nature, which will have an impact on healthy life. This kind of influence is good and bad, but it is good to say that it contributes to longevity. Whether it is right or wrong is not entirely certain. The more selfish a person is, the longer he will live. Obviously, this statement is a mistake in logical thinking. On the contrary, the longer people live, the more selfish they become. This is obviously meaningless. Selfishness is not selfish, and longevity is not proportional. More indirect and inevitable progressive relationship.

Selfishness has nothing to do with happiness, which often makes people feel that the more selfish they are, the less happy they are and the less selfish they are. That's just the opposite. Longevity is directly related to people's physical and mental health, which is the most affected, and has little to do with selfish mentality. Happiness and unhappiness have the greatest relationship with people's mentality and feelings, and have no direct relationship with selfishness. Not to mention that the more selfish, the happier.
