This is an easy and quick test.

Count how many “F” are in the following text:

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

Done? Okay, scroll down only if you counted all the “F”

How many? Three?

 

Wrong, there are 6 “Fs” No joke. Count again.

The brain cannot process “OF”
If anyone has found 6 “Fs” he/she is a genius.
Rare to find more than 3 and less you were just not paying attention…
