Jack is my friend. He likes playing computer games very
much. He often sits in the same way for too long without moving.
Now he has a headache, sore eyes and a sore back. He doesn't
sleep well at night, so he feels tired every day.
I think he should take breaks away from the computer. He
shouldn't use the computer for a long time. He should do eye
exercises to relax his eyes and go to bed early at night.
I think if he has a good rest, he will feel well soon.
