One question eye test for Alzheimer's

Since the psychopath test was so popular, here's another one for you. Make sure not to give away the answer in your responses, or else those of us that check the "Active Topics" list may not get the full experience.

Here goes:

Count the number of Fs in the following phrase:

FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTI-
FIC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS...

O.K., how many did you get?

Warning, Spoiler:

Well crap, I even double counted and still got it wrong.

I got 6 the first time, then doubted myself and recounted and got only 3. How weird is that?

Got it right the first time... What does that mean?

I didn't get the normal or correct number, so I guess I fall between genius and Alzheimer's, I can't remember which. $\:\)$

oddly I got "4".

6 here on first run

I missed 1 on the first time through.

Bren R.

You are all weirdos.

old school

I got 6, but I was carefully going through it

Yeah, I went too fast and got the normal answer, then slapped my head at the revelation.

Having seen this before, I totally aced it.

Like Spiff, I got 4 the first time, then recounted and found the of's. $\:\)$

There are 3 ofs. How did you guys get 4 the first time?

9.
