In fact, I don't prefer to any sports in particular, neither do I believe in any health care products, so the only thing I do to keep healthy is going to bed and getting up early. It seems that it's easy to go to bed and get up early, but actually it's not the case. Nowadays, an increasing number of pressures from study or other aspects of life make it hard for us to do so. Firstly, going to bed early is not easy to do. For example, when some of my classmates stay up late preparing for an exam, I will feel great peer pressure. More than once I have the impulse to lea m from them and stay up late together with them. And lots of temptations such as computer games make it worse. Sometimes all the people in the dorm stay up late engaging in those mindless activities. But I am usually able to control my impulse and desire to go to bed late in the last minute and stick to my own lifestyle. And, early to rise isn't that easy either especially in winter when it's comfortable to linger under the covers. I sometimes manage to do so by convincing myseIf of the benefit of early rise. In this way, I've kept sleeping 7 or 8 hours a day for years. I think early to bed and early to rise can help me keep healthy physically and mentally, and can avoid wasting electrical power as we 11. So, it has become the only thing I do to keep healthy, and I am proud I can do so because it al so requires considerable persistence and strong will.
