Entertaiment is the practice of diverting and amusing oneself, or evoking feelings of pleasure and enjoyment. It can be based on almost anything, from watching movies and TV shows to playing games or sports. The idea behind entertainment is to provide a form of recreation and respite from the daily grind, allowing people to forget their troubles. Entertaiment can be adapted for virtually any scale, from an individual choosing their own private entertainment to an elaborate banquet, or from a small group of friends to performances intended for thousands.
Entertainment often hits on themes that the human brain was evolved to deeply react to, such as social backstabbing and murder. This can trigger the brain to release seratonin and dopamine which helps with happiness and well-being.
