At present, what I want to vomit most in college life is morning exercises, because the courses of college students are relatively loose, and there is often no class in the first class in the morning. However, when there is no class in the first class, I go running at 9 o'clock every day. I don't know what to do after running. I will go back to sleep, but I have a class later, but I won't sleep. This time is wasted.
