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)

The reasoning behind is further down.
The brain cannot process "OF".
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.
