People who belong to cattle are born nerds. They are diligent and pragmatic. When I was a student, I was a good boy in the eyes of a teacher and a nerd in their eyes. Because he is an introvert, he doesn't like to talk. In fact, they are not nerds. People who belong to cattle actually learn mathematics very well. As we all know, students who are good at mathematics and physics are generally not hard-working children. They are cows with very good thinking and strong logical reasoning ability, and they all like math and physics very much. Of course, physics and chemistry are cows' favorite subjects, and those about principles attract them very much. Cows are really lonely people. They are very patient, creative and practical.
