People become involved in crime when they are around criminals and have criminal attitudes in their social circle. As they get older, making new connections, having jobs, and taking on responsibilities can make them less likely to commit crimes. Life events such as getting a job or getting married make them care more about following the rules of society. When behavior is rewarded or punished, it affects how likely they are to commit crimes. Learning ways to change criminal thought patterns can help someone stop committing crimes. So, being around less crime and more positive influences can make people stop committing crimes as they get older.
