Count every F in the following text:
FINISHED FILES ARE THERE
SULT OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH
THE EXPERIENCE OF YEARS.
How Many?
There are 6!
Read it again!
Really, go back and try to find the 6 F’s before reading on.
The reason is that the brain usually skips the word ‘OF’.
Three is normal, four is quite rare.
Send this to your friends.
It will drive them crazy
And keep them occupied
For several minutes!
