I am doing activities every day. It seems that there are no problems with me. I can perform a lot of physical activities very well, I run every second day, and I can not admit any problem. But problems begin when I start to play soccer, basketball or some other sport game. I get out of breath very quickly and feel vary tired. I simply can not understand. Ma-by it is due to stress or something? Please help..
