why can't we...play games all day long?

The question is, why can't we play games all day long? Well, I wish that we could play games all day instead of staying inside and pretending we know what we're doing with all the technology and that. But, there is a down-side of playing games all day long, unless we play learning games, there's not really any learning involved so we won't get a very good job when we're older. I know that games are fun though and we all play them on technology or with friends at school. I know I do! Another reason why games are not all that suitable for playing all day long is because... wouldn't you get bored? I mean, there would be a point where everyone would get bored with playing games that they made up themselves or playing outside games. Okay now it's staring to sound like a "why we can't play games all day long?" so this is why I really want to play games all day long... the teachers can relax a bit knowing that the class is all happy and under control for a while. Also, it will be a better learning environment for the classroom and we all know why!
