Playing chess is a sport. Isn't it?

In daily life, we need to do sport to make our body healthy. Everyone with their interest have their own fondness in sport like running, jogging, swimming, etc. I have my interest in playing chess. I believe that you think of playing chess is it just a game and it is not kind of sport. I do. But, do you know if playing chess is same with the other sport? No. I know that you will say it. It must be different because when you playing chess then all you can do just sit down and do not do something physically. Of course, it different with sport like swimming that you have to do it hard physically. But, If you playing chess seriously and think hard to make the strategy, you will burn your calories much. Very much. It can be called as a sport because this game burns calories much like the other sports do. Playing chess also need much strong mentality like the champion in the sports have. Playing chess must have good control in emotion with psychology because it have much contribution in it and can't be separated. Strategies you make must have much possibilities because one strategy doesn't enough to make it win.
