ack 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.
