and don't cheat...

Here's an interesting diversion for two minutes.
A quick test of intelligence. Don't cheat! If you do, the test won't be fun.
I promise, there are no tricks to the test. Read the sentence below:
FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTIF-
IC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS.
     
Now count the F's in that sentence. Count them ONLY ONCE.
Do not go back and count them again. Scroll to see below...
     


















     
     
     
     
     
     
     
ANSWER:
There are six F's in the sentence.
A person of average intelligence finds three of them.
If you spotted four, you're above average.
If you got five, you can turn you nose at most anybody.
If you caught six, you're a genius.
There is no catch. Many people forget the "OF"'s.]
The human brain tends to see them as V's and not F's!
Pretty weird, huh?
Pass this on to anyone you feel would enjoy this.
