Unfortunately, several diseases out there still don’t have a cure. Most of them have symptoms which will affect people’s lives to a certain (sometimes extreme) degree. Some of them can be very annoying, crippling, or simply terrifying. Some of them, for example, are sarcoidosis, tinnitus, genital and oral herpes, asthma, myasthenia gravis, menopause, and so on. People with such conditions are especially vulnerable and more willing to be gullible, since they often feel that the medical world “fails them”.
