Test Your Brain

This is really cool. The second one is amazing so please read all the way though.

Count every "F" in the following text:


FINISHED FILES ARE THE 
RESULT OF YEARS OF SCIENTIFIC 
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 brain cannot process "OF".


The reasoning behind is further down.
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.



p/s: MI count 4 F on the 1st go..^^
