Entertainment is a broad category of activity that can include anything from a comedy show to a museum exhibition. People tend to enjoy different types of entertainment depending on their moods; some may prefer lighter fare like cartoons or playgrounds, while others might seek more thought-provoking or educational forms of entertainment such as documentaries, puzzles, or strategy video games.

Entertaiment often hits on topics that the human mind was evolved to react deeply to, such as social backstabbing and murders, and can trigger the brain to release seratonin, dopamine and other feel-good chemicals. It can also be a good way to keep the brain sharp and active.
