Well, it’s like a kind of magic. Scientists have a special kind of wisdom, I suppose. Clearly, what the CDC says, at least on one topic, is incorrect. You can tell who’s going to be HIV positive – just by looking at them.

“Warning: This test will not tell you if you’re infected with a virus. It may confirm that you are pregnant or have used drugs or alcohol, or that you’ve been vaccinated; that you have a cold, liver disease, arthritis, or are stressed, poor, hungry or tired. Or that you’re African. It will not tell you if you’re going to live or die; in fact, we really don’t know what testing positive, or negative, means at all.”
