I suspect most people realize that a column on a given topic, such as this one, is (a) a column; and (b) on a given topic. The former implies that there is more to it than just a single point or statement, such as: tobacco is bad for us; crime doesn’t pay; obesity is mostly preventable; lifestyle is medicine. Those are all true, but they are simply points without argument or context. A column makes an argument, and provides context. It tells a story.
