testing...

A new client of mine gave me this test to take as we met yesterday:

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...

How many "F's" did you find?
did you get 3?
or did you get more?

Please leave your answers in the comments section. It's pretty fascinating.
