Alzheimer's eye test

I found this a while ago, and I don't know if the reasoning is true, but everyone that has seen it to so far has had the same answer!

Alzheimer's Eye Test (Submitted by LM Hawes Leighton, A)

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 ?



...................... 3?

WRONG, THERE ARE 6 -- no joke.
READ IT AGAIN !

Really, go Back and Try to find the 6 F's before you scroll down.


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.

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