I think sleep is really a very important thing, in the past high school junior year in order to read often lack of sleep, the next day of the spirit is very poor, the concentration of class is significantly reduced, I tried one day after full sleep, the spirit of the next day class is very good, even the content of the teacher's lecture is clearly remembered in the mind, really verified the power of sleep.
