Entertaiment is the act of amusing or diverting someone. Many types of entertaiment can be found in different media, including books, movies, video games, television, music and live performance. Entertainment often hits on the deep emotions that the brain was shaped to react to. This can include social backstabbing, murders and other themes in the social world which we were molded to understand. Entertaiment can often trigger the release of seratonin and dopamine. This gives a good feeling because the brain was shaped to understand these feelings.
