1．Playing video games can be a fun way to spend time with friends.In some schools，teachers use games like Minecraft to encourage teamwork and communication.
But for some players，gaming is an unhealthy habit.They stay up late playing games.They do little or no homework.They give u other hobbies and pay little attention to their families and friends.The video-game world seems a friendlier place than the real one.

Not all experts agree that over-gaming should be called a disorder.They say people who spend too much time on video games may develop other mental health problems.These should be treated first Others think WHO did the right thing.Clifford Sussman is a doctor who treats gaming addiction （癮）.He says those kids often get angry easily and it makes everything difficult for them to complete，like schoolwork.
Sussman advises tracking （跟蹤） how long you play.He says you should take at least an hour-long break after every hour of play.The brain needs time to recover.
Young gamers who think they might have a problem should ask an adult for help.Sussman suggests you first answer a simple question： "Are you in control，or is the game in control？"
