A blind squirrel rarely finds nuts...hence why they die and you don't see many of them. However, that does not preclude the possiblity of a blind squirrel finding a nut or two, and thus surviving. Retech, has, repetedly, compared two numbers and worked out which was larger, yet, recently, failed. Retech may have never failed to compare two numbers before, yet it happened...Therefore it is possible for something which hasn't happened, to happen... THEREFORE, either, you have been insanely lucky(which is unlikely, since you know many things), or you have not been unlucky in the past...Afterall, many squirrels die despite their perfect eyesight. My point is that holding up a test as proof of intelligence is a flawed concept...it is a proof that you know what the test asked you and you got correct...nothing more.
