How many F's ?

HOW SMART ARE YOU?

Read this sentence:

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

Now count aloud the F's in that sentence. Count them ONLY ONCE.

Do not go back and count them again.

There are six F's in the sentence.

One of the average intelligence finds three of them.

If you spotted four, you're above average. If you got five, you can turn up your nose at most anybody.

If you caught six, you are a genius!

There is no catch. Most people forget the OFs. The human brain tends to see them as "Vs" instead of "Fs."
