There are a great many hobbies to choose from. Some people enjoy collecting coins or stamps, others choose to spend their time on sports or music. I have many hobbies, but playing basketball is my favorite one. At weekends, we always build a team to play basketball against another one in our neighbourhood. The competitions brought us so much n. I think playing basketball is a good way to build up one's body and relax oneself. But I will always remember that it's unwise to spend too much time playing.
