Most of Us Enjoy a Good Joke!
To quote from psychologytoday.com: "Although laughter is not generally under voluntary control, yukking it up has numerous health benefits. Bouts of laughter can boost the immune system, relax muscles, aid circulation, and protect against heart disease. They abet mental health, too; laughter can lower anxiety, release tension, improve mood, and foster resilience. Of course, laughter also enriches the social experience by strengthening relationships, helping to defuse conflict, and allowing people to successfully operate as a team. The benefits of laughter, for both bodies and minds, show that contagious convulsions are anything but frivolous."
