How does video games affect people

Playing video games or going on the laptop before bed isnt 'bad' for you, but it will be a lot harder to get to sleep as you will still be in your video game world - trust me I know - Your eyes instead of feeling tired and relaxed pop open and you find yourself trying to get to sleep with your eyes open.
As well as this, they've given me a really bad headache after going on them for a couple of hours a day. It is also quite bad for your eyesight as you have to strain your eyes - although others may argue that reading a book also does this...
Video games aren't 'bad' for you, there just not very good for you. The fact that you're sitting on your bum, and not getting much excersize isn't a nice thought.
We can all play video games without it really having a big impact on us - but playing them for a long stretch of time is bad for you.
As well as this, some people can go to extreme measures, as to living in the game world and almost forgetting to live in the real world because the whole time there not on the video game they are only thinking about going back on it. But, going on it for a half an hour a day as well as getting excersize probably wouldn't have a big effect at all.
Hope this helps.
