This is an ALZHEIMERS EYE TEST Count every " F " in the following text: FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC STUDY COMBINED With THE EXPERIENCE OF YEARS. HOW MANY? 3 ... or 4 ... ? WRONG, THERE ARE 6 -- no joke. READ IT AGAIN! Go on read it again. Really, go Back and Try to find the 6 Fs before you scroll down. The reasoning behind this is further down. Apparently the brain cannot process "OF" Incredible or what? Go back and look again!! Anyone who counts all 6 "Fs” on the first go is a genius. Three is normal, four is quite rare.
