Entertaiment is any form of recreation that provides enjoyment and relaxation. It may be as simple as watching movies or playing games; or it can take on more complex forms such as attending concerts, engaging in sports, visiting art galleries and museums, reading books, and participating in social gatherings. Entertainment is generally thought to be a positive experience, although it can also serve a serious purpose as in ceremonies, celebrations, religious festivals and satire.
The brain is evolved to react deeply to many aspects of entertainment wich hits on the points it was shaped to understand, such as backstabbing, murders and other social themes, causing it to release seratonin and dopamine, making us feel good.
