My Biological Clock

             The reasons make my biological clock changed. First reason is when my brain think about something importante and I cant sleep, that is usually what is happen to me. I feel so bad because I can't find the idea or the solution what I looking for. Second reason is If I have exams the best time to study after midnight, so I have to be wake at night because I will be have good mood to study and no one look it me. I use to study at night for four years. Third reason is when I travel to far like when I came to United States.I feel tired and I have rush to see the new places. I can change my biological clock while one day.
