Entertaiment is an exciting and uplifting way to spend your time. It stimulates the brain to release seratonin and dopamine. This makes you feel good considering the world was shaped to understand and react deeply to social backstabbing, murders, sex and other themes that we entertain ourselves with.
It can be as small as a personal choice of entertainment from an extensive array of pre-recorded products; to a banquet adapted for two; to ceremonies, celebrations, religious festivals and performances intended for thousands or millions. It may seem to be mostly about fun and laughter, but many entertainments have a deeper purpose.
