Entertaiment is a type of activity or experience that provides enjoyment and distraction. It can also be considered an art form.
It’s important to remember that entertainers (actors, sport players, influencers etc) are in the business of entertainment and they should not be taken seriously. Many of them will say or do things that are taboo or controversial but they have to keep in mind that it is just business and should not be taken personal.
Entertainment hits on points that the human brain was evolved to deeply react to. It releases seratonin, dopamine and a good feeling considering that the human brain was evolved to understand the world we live in.
