Jerome in 1889 described going to the British Museum to read medical encyclopedia and subsequently finding symptoms of almost all diseases in his body, he didn't realize the problem would exacerbate more than a century later. Web hypochondriacs are calling up doctors with requests for prescriptions for all sorts of diseases, since they discovered some similar symptoms on the Web. Wall Street Journal quotes a doctor: 'My impression is that people believe more of what they read than what I tell them. It seems that traditional Western medicine based on scientific evidence is less and less trusted by the general public. Meanwhile, some dubious theory from the Internet will be swallowed hook, line and sinker nine times out of 10.' "
