For example, scientists have found that the first time a person yawns is within the 11th week of the Matrix. In addition, the survey shows that men yawn longer than women. 55% of people yawn within 5 minutes when they see people yawning around them. Even when a blind person hears someone yawn, he will follow a fight.

Even a self-conscious gorilla will be affected by the yawning of others.
In addition, Dr. Stephen also found that yawning is related to human character. Those who are susceptible to other people's influence, often attributed to bad moods and other reasons, are most susceptible to yawning, and those who like to take on their own will not be susceptible to contagion.
