For an analogy, the world is an elephant, and we human being are a group of blind people. Human being can not see what the elephant looks like, however, they are still curious about what it is. Those who are curious about the ears of elephant become earicians. Those who are curious about the legs of the elephant become legicians. As time pass by, legsicians were devided into leftforelegicians, rightforelegicians, lefthindlegcians and righthindlegcians.

When earics and legics were invented, the study of them both started from what-balahbalah-of-the-elephant-looks-like, why-balahbalah-looks-like-that, and how-to-do-when-we-meet-balahbalah.

The reason why it is so hard for me to decide which area to study further in the future is that I am curious not only about what the legs of the elephant looks like, but also about why its trunk can spray water. Also, I want to know how it communicates with othet elephants. Wait, are there any other elephants？If none, where this single elephant came from？

In short, I am curious about everything of the elephant, not limited in some parts in it.

I am curious about the whole world, not limited in some areas in the world. soa natural?
