I have a friend who named in jack.He is crazy for playing computer games.He often sits in the same way for too long because he is absored by the games.Now he had a serious headache and a badly sore back.I think he is almost sight-seeing.He does not want to go too bad instead he is very tired.So he can not study hard every days.

 

　　I have some advice for him.He should take enough breaks.He should not play computer games for so long.I think if he always do that,he will really sight-seeing.

 

　　If he have a good rest,he will be good.Action speak lpuder than words.He have to do this by himself.I hope he will be OK.
