Why are there two children with strange tempers on their heads? Is there any physiological basis?

Physiologically, there is no evidence to support it. It's weird to have two spinning children on your head.

The formation of spin is only related to the distribution and direction of hair, and the formation of temper is related to congenital inheritance, as well as the acquired growth environment and educational environment, which have nothing to do with spin.

Of course, if the environment and people reinforce this impression, it is indeed possible that two children who are spinning around will be more eccentric. Here's the process. An ordinary child has two rotating circles on his head. People think he is eccentric, and his normal behavior may also be evaluated as eccentric. Then this stereotype leads the child to think that he is eccentric, and then he becomes accustomed to it, and will show more eccentric behavior in his later life, thus leading to a real eccentricity.
