A Quick eye exam

This will blow your mind
Just try it but no cheating!
Count the number of F's in the following text:

FINISHED FILES ARE THE
RESULT OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH THE
EXPERIENCE OF YEARS



Managed it?



Scroll down only after you have counted them!










OK?





How many?


Three?

Nope, there are six - no joke!
Try again!


FINISHED FILES ARE THE
RESULT OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH THE
EXPERIENCE OF YEARS


The reasoning is further down...
The brain can’t process the word "OF".


Anyone who counts all six F's on the first go is a genius
Three is normal.
