Try this only once and be honest... This is not a joke, but a true 
test.

Read the following sentence:
FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIF-
IC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS.

Now read through the above sentence counting aloud the "F"s as you find
them (1...2...etc).  Count them ONLY ONCE:  Do not go back and count
them again!!.

OK - GO!





See below for answers ...












ANSWER:

There are six F's in the sentence. 

 One of average intelligence findsthree of them. 

 
If you spotted four, you're above average.

  If you got five, you can turn your nose at most anybody.  

If you caught six, you are a genius.  

There is no catch.  Many people forget the OF's.  The
human brain tends to see them as V's and not F's.  Pretty weird, huh?
