Humor and laughter are important for quality of life and human survival. It can be a stress reliever or stress producer since what is funny to one person may not be funny to another. It can be used as a relationship builder or alienator. Some people have a great sense of humor while others have a "sick" sense of humor, and their humor can be destructive and hurtful to others. Jokes can be funny yet hurtful forms of communication. Here are some links to websites on the subject:
