Sports

Humans invented sports to enjoy their animal characters.

Humans cannot forget their living in the forest. The forest gave immense freedom of activity and he was close to an animal. But society conditioned him as a conditioned slave. He loves to be an animal in society but laws never allow it. 

Humans never forget their tribe culture. They sit around the campfire and are replaced by a living room. Centralise kitchen becomes an individual kitchen in each house. You lived near a river to have bath and for other activity now the bathroom has been replaced with utmost privacy. In the forest you are surrounded by dangerous trees and plants. Our own garden has a safe tree and plants and what else he has not replaced. Every activity of a tribe was brought into his society life but still he has to forgo his animal character of fighting. He doesn’t want to forget. Hence he made an idea to create and exercise those in the form of Sports.

Here Sports are nothing but for humans to carry out their animal behaviour but with the approval of law.
Humans used to fight with animals or invade neighbouring tribes and kill them. Now it was replaced with the Game called Boxing. You can hit the opponent and vice versa. Both doing it in the name of the game and they signed for the later consequences and make the Game so interesting. Here more than them, you can see the animal way of shouting from the audiences who vicariously enjoy their animal behaviour.

Humans interesting job was hunting and it was replaced by Archery. If you watch the player who excels in archery before he releases his arrow the aim is more like he is going to shoot the prey. There is that much concentration in aiming not to miss the food. The food is replaced by medals and prize money and their country recognition.

Humans chased his prey, hence he knew how to run inside of forest and the same was in the running race. The swit running and hurdle running all make it as if they are running inside the forest by jumping and running again. We always experience the entire forest atmosphere inside the Games. 

We love fishing because it is one source of food made available in plenty. Fishing always brings uncertainty. Your small boat may go upside down and in order to escape from the shark and other predators, you swim very fast to reach the shore. Now this was practiced inside the stadium and your predators are your competitors.

We never forget our animal nature and we exhibit either participating or stand as spectators to experience. 
Hence humans are animals and they are never going to leave those traits even after 100million years.
