Cof, cof... Have you ever caught a cold? Have you ever been near a cat and then started coughing, and felt your eyes watering? Welcome to the club! Coughs are very common. Even though they're a nuisance, their purpose is to help us because they are a way of clearing our respiratory tract. A cough is rather like a "guard dog" for the lungs: it protects them against intruders or from enemies on the inside.
