WARNING: Medical Websites are bad for your health

Why is it that whenever you happen to wander onto one of those health websites you always end up doing one of those quizzes to find out your risk of having something? And why do you always feel ill when you read the result?

The other day I took a quiz to find out if I was at risk of having depression. I scored 15, which, according to the scale, meant that I could be mildly depressed. Reading that depressed me- not at of the thought that I could be, but of the fact that the quiz decided that I wasn't as depressed as I thought I could be. I don't consider myself to be a hypochondriac, but all these kinds of websites make even the healthiest of people believe there's something wrong with them.
