The world is a big universe, the human body is a small universe, the human body is also a very large collective, you can imagine it as a country; a home. No matter how you look at it it exists here. The basic unit of a nation is the human being, the basic unit of our body is each of our cells. Each one of us is working hard to add to the nation; the cells within our body are constantly working for our physical well-being. I wonder how many people can sense their existence.
