I am keen on football. In my opinion, this game is very exciting. It’s good for my body and for my mind. I have been interested in football since I came to school. Then I had my fist team. I usually play football a few times a week. You communicate while playing and feel emotions of other people. I like it because it’s a team game and for me it’s boring when you have to play alone. I enjoy my hobby because I can spend time with my friends and do what I want.  There is one more reason why football has become my hobby. It’s extremely popular with people. I think that it’s the best hobby.
