Keep a regular and healthy life

        Everytime I stay up for a whole night in front of a computer,I feel my biological clock is upside down. The first time I did that I could not accept it untill my friends talked me into it.   Then the second time, the third... I see how big the strength of a habit is!

     Why can't we keep a regular and healthy life? It is partly because we want some excitements. Life is too monotonous for a student who spends a whole day in the dorm room, so he wants to play computer games in the Internet Bar for a whole night. It can be understood but can't be accepted. We can find some more healthiful things to do so we can have a lot of fun while killing time. For example, doing some sports can do good to us both physically and mentally.

     Next time you want to read lying on bed or play computer games late at night, ask yourself: "Does this do good to my health?" If the answer is no,find a healthiful alternative.
