Early birds or late owls? -- Some people prefer to get up early in the morning and start the day's work. Others prefer to get up later in the day and work until late at night. Which do you prefer?

I prefer to get up later in the day and work until late at night。Maybe I always skip boring class in the day，and sleep in the morning。Sometimes I am convinced that I can learn much medical knowledge by studying alone。When I was a junior high school student，I studied myself during class without listening teacher’s words。And I can always get good grades by working hard myself。

Another reason is that I like the quiet of the night，and I can devote myself to studying and thinking many things。There is less traffic noise in the night，and I can relax my mind。Therefore，I think that studying in the night is more efficient than it in the day。That’s my major cause to do things in the night rather than in the day。

Sometimes I will spend my time looking down on the peaceful cityscape in the night from the highest floor of my apartment building。I can invite some good friends to drink alcohol there，and share some secrets in our mind。We can relax ourselves in the night with the star blinking through darkness。

In fact，I never recommend any person to work in the night。Because I think that it is harmful to health。Our immunity against virus or bacteria maybe decrease when we have bad habits。Doctors always recommend us to sleep before eleven o’clock and wake up early。Our liver will become sick without doing things mentioned above。

In the end，I will still study in the night although it’s harmful to my health。Because it is my favorite life style，and I would rather enjoy my life than live to the age of 100。The philosophy of life is that I only want to follow my desire of mind。
