It can cause countless problems among humanity, but the intention behind it is good, I mean who doesn't want to have a good laugh (apart from this emo guy who hates laughing). This can be used as a warning when you want to talk about something serious, in other words, if someone is offended by your proposition, you can defend yourself by saying you were joking. It is also used to attract friends or a special someone and can improve those relationships. It is used to relieve stress in many situations such as tough jobs such as law enforcement and the medical field. Not to mention the patients who receive the terrible news and also the prisoners who have ruined their lives. Humor is necessary in humanity so that we can sometimes keep our sanity. Additionally, its appeal can be leveraged to present important information or messages that would otherwise not be received due to news boredom. Keep in mind that humor is difficult to explain and there is still a lot to learn.
