The topic of this week is really interesting for me. When i was young, I was always thinking about how I can be a superman and save the world in the future, and after I grow up, I realized that how difficult that one people can save the world. While now in this week’s video, the speaker talked about how playing games can save the world, it really amazed me. In the video, she mentioned about playing can help people solving problems in real life. I am also a gamer. I always spend about 10 hours per week on playing games. and as far as I concerned, playing games truly helped me in some ways, like improving reaction capability, social ability and even the mental arithmetic. and for me, game is also a really good tool to relesase bad emotion and keep a healthy attitude in real life.
