What is the folk prediction of eyebrow itching?

Eyebrows itch without warning and move. The left eye jumps "disaster" and the right eye jumps "wealth". As a result, a quick glance often brings unreasonable trouble to some people. In fact, this is purely out of thin air and groundless. The so-called "saccade" refers to the saccade of the eyelid, which is due to the abnormal excitement of the nerves that control the eyelid muscles, that is, some muscle fibers of the orbicularis oculi muscle cannot contract continuously in a short time, making the skin on it jump.
