I wrote that piece in jest. It is Negative Astrology Characteristics, so some negative traits of the signs were exaggerated, in an attempt to soften the blow and make it fun to read. I was suggesting that Virgos worry too much about having health problems, and that it's silly because they usually live such healthy lifestyles. It's humor. I don't think Virgos have diseases, but they can become hypochondriacs if the sign's traits are taken to extremes. All of the sign descriptions were extreme; it was supposed to be a fun piece, so please don't take it so seriously.
