Most hobbies are just as dumb when you think about it.
Sports = watching grown men play with balls,
Games = giving yourself unnecessary problems to solve,
TV/Reading = learning (usually) completely useless information
watching sports is entertaining as you're watching highly skilled individuals perform at the highest level + gives you a sense of belonging; games - entertainment and skill development, whether those are multiplayer games that teach you cooperation and competition, or single-player games that is fun and in a lot of cases learning (through lore), developing motor skills, strategic thinking and so on; tv/reading - learning (nothing is useless information, it helps create more connections in your brain);
yet, sitting in ketchup is brainrot content - 0 value
