Count the F's

1) Slowly read the sentence below:


FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTIF-
IC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS


2) Now go back and count the number of F's in the sentence.


Don't peek until you have finished counting!



































Did you get three F's?  Most people do,

but it's NOT correct!  Go back and try again.




















Did you get four F's?  Some people do,

but it's STILL not correct!  Go back and try again.




















Did you get five F's?  Some people do,

but it's STILL not correct!  Go back and try again.




















Yes, there are actually SIX F's in the sentence!

Somehow we see the F in OF as a V instead.

People rarely count more than three of the F's.
