Let’s test your brain

Today I would like to let you test your brain. You will know it’s not easy.

Count alphabet “F” in the sentence below. You can count it only time. Please carefully.
Let’s go.

FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC STUDY COMBINED WITHTHE EXPERIENCE OF YEARS...

How many “F” you can count? If you can not count it to 6, you are wrong.
I allow you to count it again… and then you can find it has 6 “F”.

The cause that you can not count to 6 is your brain can not get many words “of” in the same time. If you can count it to 6, that means your brain is very genius.
If you can count it to 5, that means you are excellent.
If you can count it to 4, that means you are clever.
If you can count it to 3, don’t worry. Your brain is normal.
If you can count it to 2 or 1, you should to check your brain, more over you should you check your eyesight too.

I can count to 3, how about you?
