In this article, it was assumed that people who switched from planes to cars after the terrorist attacks did so because of fear. However, many people who switched probably did so because of the inconvenience of added airport security. But before these extra deaths can be blamed on fear, security, or something else, it is […]

Your article gives American beef eaters a false sense of security. Yes, only 1 cow out of the 20,000 tested has been discovered to have bovine spongiform encephalopathy (BSE).

I do not know about the rest of your readers, but I do “hear” at least some low frequency sounds, but not with my ears. The nerves in my feet feel these vibrations and my brain parses the sounds to my flight-or-fright processor before I can process any conscious perception. Ray BryanSt. Paul, Minn.
