Chess and billiards are not sports

Through human sports history, organizers never considering have billiards and chess into the competitions, no matter where those organizer come from. Also, I strongly believe those games are not recommended into any kind of sports.
At the first thoughts, whenever people think sports, they will more concern about the will combination between the maximum human body power and the natural of human body. If we justice start form the body part usage, those two games are less relative to the body movement but more to the brain competition. In this case, billiards and chess should belong to its individual competition, but which is going to be different with sports class.
Secondly, some people who saying those two games are more like to be sports by the game are thinking because of players are using their fingers during the competitions. But in another hand, in any other kind of sports, all of the athletes are definitely using their whole body combine to finish every part of competition. Such as basketball players using the well coordination to score for their teams, as well as in swimming, football, baseball, boxing, hockey, table tennis, water polo, diving, sailing games. In addition, all of those samples are using their complete body to show their natural talent and power of coordination. Then those two arguing games-billiards and chess whether should be in the sports or not in the sports competitions. To the results of compare between those games in the Olympic Games, chess and billiards become fewer activities movement then others.
In general, in the way of justice sports, I am more looking at the greater percentage between using the brain using and the bodies participate. Then for the regular sports, such as in the football, volleyball games, athletes are more use their bodies to against each others. But if we look at the billiards and chess is less. In addition, the main reason of keep those two games out is that those two games are not entertainment enough, therefore not enough fun to a lots of audience, the people who interesting the chess become limited, the number of audience will not as much as in other games.
