Entertaiment is a word that refers to anything that entertains. It can be something as simple as watching a movie, or as complex as being involved in an artistic performance. Whatever the case, entertainment can be a great way to have a good time and make people laugh. It can also help to relax the body and mind. Besides, it can help to release seratonin and dopamine which are chemicals that the brain needs to function properly. The main reason for this is that the human brain was shaped to respond deeply to certain things in order to survive and navigate the social world.
