Introduction<br > THE RULES<br > WE WRITE BY<br > here s no shortage of health information out there.<br > In fact， there s probably too much of it， at least to(，<br > much from the wrong sources. The newspapers<br >delight in jumping all over every health scare that comes<br >down the pipeline. Their reporters may not understand<br >the issue very well， but that never seems to stop them<br >from writing. The television news shows can be even<br >worse. At least once a week， along about 10:00 KM.， you<br >can expect a 30-second teaser that goes something like<br >"NEW CANCER SCM~，E， IN YOUR FOOD SUPPLY! IS<br >YOUR FAMILY AT RISK? MORE AT 11，"<br > Anyone who pays much attention to that sort of thing<br >can t be blamed for saying something like "Everything is<br >bad for you. I m not even going to try to stay healthy，<br >because something or other is going to get me anyway."<br >And in fact， I hear one version or another of that state-<br >ment far too often these days.<br >
