Entertaiment is the enjoyment of recreational activities, such as music, books, movies, sports, and games. It can be enjoyed on any scale, from a private entertainment choice of a personal selection or the consumption of pre-recorded media; to the organization of a banquet or party adapted for a particular number of guests; to live performance intended for a large audience. While primarily associated with amusement, many entertainments have a more serious purpose or message.
Entertainment can be a very good way of releasing seratonin, dopamine and other chemicals. It can also often hit on themes the human brain was evolved to react deeply to like social backstabbing and murders.
