An F'n Eye-Brain test! really!

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 F's DID YOU FIND ?




ODDS ARE YOU ARE WRONG, THERE ARE 6 -- no joke. Most don't see them all.
IF YOU DID NOT READ IT AGAIN !
Really, go Back and Try to find all 6 F's before you scroll down now.


The reason is further down.




Some peoples brains cannot process "OF" as having an F.
Incredible or what?
Anyone who counts all 6 "F's" on the first go is in the minority. Three is normal, but even seeing four is quite rare.

Send this to your friends. It will drive some crazy.!
And keep them occupied... For several minutes..!
Enjoy!
