Try the test - it's quick.

Count the "F's" in the following text:

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

Managed it ? Scroll down only after you have counted them, okay?

How many ? 3? Scroll down....

Wrong, there are 6 !!--no joke.

Read it again.

The reasoning behind is further down.

The brain cannot process "OF".

Incredible or what ?
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 drives
them crazy.
