  People of the four blood types A, B, O, and AB are both smart and stupid.

  In terms of probability, people with AB blood type are generally the smartest.

  The biggest characteristic of people with AB blood type is that they are romantic and full of fantasy, so they are very imaginative; their observing power often finds the peculiarities of things in an instant, so AB people are always regarded as weird by everyone. The reason is that He can always find your mistakes (such as the trouser door zipper is not closed, one side of the earring has fallen, etc.), and it makes you embarrassed to say it; generally, their memory is superior, and other blood types are incomparable. But because this blood type is introverted, passive, and unassuming, it will not show up in general occasions and make people careless.

  Conclusion: Of course, the above statement is just an argument. Innate intelligence will not succeed without acquired effort. A wise philosopher once said: "Someone scolds me on the street. I don't even look back. I don't want to know this boring person!" For your own desire, let's talk about it first by learning the skills steadily. So no matter what blood type people are the smartest, we should learn knowledge down-to-earth, especially when we are young, we must go all out to learn skills and not be distracted.
