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 ?




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 brain cannot process 'OF'.



Go back and look again!!
Anyone who counts all 6 'F's' on the first go is a genius.
