Jack is my friend. He like piaying computer games very muck . He often sits in the same way for too long without moving .Now he has a headache and a soreback .He does not sleep well at night ,so he feels tired.

I think he shouldlie down and rest .He should not use the computer for a long time .He should go to bed early at night

I think if he has a good rest ,he will feel well soon .
