Gawker reports: When Belgian science professors ran bacteriology and toxicology tests on the 10 most popular books checked out at the Antwerp Library, they probably expected to find a few stray germs. They found herpes. According to the two university professors who ran the test, trace amounts of the herpes virus were found on copies of "Fifty Shades of Grey." The amounts of the virus were so small that they posed no real threat to humans, but maybe we should think twice before we borrow an erotic novel from the library. All 10 books also tested positive for trace amounts of cocaine.
