Entertaiment is entertainment for a large range of people. It can be art, music, sport and many other things that give a good feeling. It can also be very serious and deadly. It is important to note that the concept of entertainment is very personal, what one person might deem enjoyable may be very disturbing for another. This is because we have a very different mind shaped to understand our world. A lot of entertainment is focused on social backstabbing, murders and other themes that the brain was shaped to react deeply to in order to function well in a social world.
