Do you always feel tired? If so, you should have enough time to rest. If rest doesn’t work, you should go to see the doctor. Doctors will tell you something about your health. In our life, people are busy working, taking care of families and doing a lot of things. Sometimes we forget our health. We just keep working and working. But when we find we’re sick, it’s too late. We should not keep ourselves too busy every day. We should learn to balance (平衡) work and health. Work is important. Health is more important. If we lose a job, we can find another. But if we lose health, we will never get it back.
1．We should have enough rest if we are tired.2．We always forget our work.
