Entertaiment is a multifaceted category that encompasses everything from escapism to cerebral engagement. People can find entertainment in a wide range of mediums, from art exhibitions and concerts to video games and puzzles. For some, a comedy show might be their idea of fun while others might prefer the suspense of a murder mystery or the mental challenge of a strategic game. The fact that so many forms of entertainment can evoke such a wide array of emotions, from joy to sorrow, makes them uniquely suited for catharsis and emotional cleansing. They can also hit on deep emotions that our brains were evolved to react to in order to understand the world around us.
