ALZHEIMERS' EYE TEST Count every " F" in the following text: FINISHED FILES ARE THE RE SULT OF YEARS OF SCIENTI FIC STUDY COMBINED WITH THE EXPERIENCE OF YEARS... (SEE BELOW) HOW MANY ? WRONG, THERE ARE 6 -- no joke. READ IT AGAIN ! Really, go Back and Try to find the 6 F's before you scroll down. The reasoning behind is further down.       The brain cannot process "OF".  Incredible or what? Go back and look again!! Anyone who counts all 6 "F's" on the first go is a genius.  Three is normal, four is quite rare.
