Entertaiment is the performances of plays or films, and activities such as reading or watching television, which give people pleasure. It also stimulates the brain to release seratonin, dopamine and other chemicals. Entertainment is often about social backstabbing, murders and other themes that people find important to understand in order to live and survive in a social world. Besides the pleasure it gives, it is also useful for people to learn how to cope with problems, such as illness, stress and conflict. It is also useful for children, who use it to mimic adult activities and develop skills they will need as adults, such as motor skills and social interaction.
