My name is John Doe, and I have asthma. I am concerned about my health, and I’m not sure whether I should take the steroids and other chemicals my physician has ordered me to. A friend suggested I should take magnesium. What shall I do? Well, I’m up-to-date and concerned, hence I consult the World Wide Web. I search for “asthma and magnesium,” and find … > 26,600 Web page matches! When looking for “corticosteroids and asthma,” or even for, eg, “anticholinergics and asthma,” I “only” find 17,400, and “only” 2,370 Web sites relate to anticholinergics and asthma. When browsing through the 26,600 pages, the evidence in favor of magnesium seems overwhelming. My friend was right: I should take magnesium!
