I like midnight hours,too. Just as what you said, night time can let me make the use of time, especially for the studing. But I also worry about health when I burn the midnight oil. Liver sickness seems to be worried about most. Suggest everyone go to bed during the 11 o'clock in the evening to 2 on the next day early moring, because it is said to be a time for our body to renew. Though I am also a night owl,but I really hope to form a habit of early to bed and early to get up. Now usually I won't surf the Internet among this four hours.
