Why do people find sports appealing?
Because of our ancient past.
Even though we have all this technology, us humans are still physically several thousand years in the past.
It is essential that we get exercise to maintain our bodies. That is why sports are appealing to most people. It is in our genes to keep our body mainained so that the muscles do not fade.
It is probably something that is fixed in our genes as a survival instinct, since we need to be fit in order to hunt for food.
