Iq is a comprehensive product of wisdom and business situation, which is unique to human beings. Because in the long river of historical evolution, other animals are evolving their own survival instinct, and the evolution of all bodies and habits is based on survival and reproduction.

Different from human beings, in the evolutionary history, human beings are a seriously degraded group, including physical fitness, viability and natural instinct. However, the human brain is at the top of the chain of biological wisdom, but it is the only place worth showing off. In other places, it can be said that pigs and dogs are inferior. This is a fact.

Human intelligence begins to develop at birth, and after a period of development, sudden increase, stability and fixation, the brain will enter the stage of decline, aging and death.

1-5 years old is developing, 6- 15 years old is suddenly increasing, 16-25 years old is stable, 25-38 years old is fixed, 39-48 years old is declining, and 49-65 years old is aging.

Then your wisdom in your twenties is only about 16 years old, which is wrong.

You said you couldn't learn a driver's license and couldn't remember so many questions. My family is fairly well off, but I can't find a girlfriend. I know nothing, and I don't know much about law.

Then, I want to ask, if you can't talk about your girlfriend, it's because you don't have enough emotional intelligence. If you don't know legal knowledge, it's because you haven't been in contact with it, right? If you can't remember the question, it's because you have a bad memory, right? A driver's license is not a poor understanding, is it? So what does this have to do with IQ?

I think you should relax. I guess you don't have any job now, so you can learn more. Throughout the ages, many people with poor memory and understanding have become celebrities. Too smart people are often smart enough to ignore everyone.
