Marriage is often considered a sign of "settling down." Recently, a study by the University of Michigan in the United States confirmed the scientific validity of this statement. Researchers found that married men were significantly less likely to engage in impulsive and violent behavior (fighting, drunkenness, etc.) than single men of the same age.

The researchers first conducted a 30-year follow-up study on 475 problem teenagers and found that marriage reduced the criminal behavior of these people by 35%. They then surveyed 289 pairs of male twins, recording their marital status when they were 17, 20, 24 and 29 years old, and filling out some questionnaires about violence and illegal activities. The results showed that among the twins, the married twins were significantly more peaceful than the unmarried twins, were calmer after an incident, had stronger self-control, and were less prone to violence.

"This is partly because good men are more likely to get married, and also because marriage can make men mature." Dr. Porter, the leader of the study, said that family responsibility, women's gentle attitude and changes in social identity, These are all factors that make men change.
