My feeling now

With After finishing two reports for two Chinese lessons, a busy day is about to be over. NOW, I am hungry. I am tired. My eyes are dry for after wearing a whole day's contact lenses the whole day.（隐形眼镜）. Because of the contact lenses, I feel sleepy. Even though, my brain keeps thinking: what is left undone? What do I have to should I finish tomorrow? What should I eat for dinner? Haha, that's funny. It seems that food is the best thing to make your brain active. Is that true?
