Drinking 5 Coca Colas a day cures all cancers. Since you have no studies proving that I'm wrong, then I should be given the benefit of the doubt? Extraordinary claims require extraordinary evidence. If the "Brain Training" crowd can't provide any conclusive and scientific evidence that this stuff does what they either say outright or imply strongly depending upon how "on the record" they are, I don't see why we shouldn't presume that it is all quackery until proven otherwise.
