Flu this!

Having a flu is like having a lesson in anatomy. The virus moves around the human body as if it were a nosy tourist. The nose runs, the head aches, the joints hurt, the stomach upsets, the lung and throat itch, the eyes water, the mouth swells, the muscles tighten and the temperature goes up and down without apparent reason. Medical students should suffer thus, that way no one would fail anatomy. There can be no better study aid.
