It's your choice, of course, but it now looks as the case in Washington state has been traced to tainted feed from Canada that was sold before we enacted new legislation to tighten up the controls on cattle feed. In other words, that particular problem is now corrected.

I think most people simply are not very good at judging risk. AIDS is not even in the top 10 of deadly illnesses, I believe; there are diseases most of us have never heard of that kill far more people in North America every year than AIDS ever did. We freak out about AIDS because it's been so hyped by the media; yet most of us go happily on eating McDonald's Big Macs and fries, tailgating other drivers on the freeway, or doing other things that are far more likely to kill us, mostly because it's too much trouble to change.
