Another example is this sentance:
Count every 'F' in the following text:
FINISHED FILES ARE THE RE
SULT OF YEARS OF SCIENTI
FIC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS...
How many F's did you count? Wrong! There are six of them above - no joke. Now read it again with more precision. Really, go back and try to find all the six F's before you continue to read this explanation. The reasoning is really intersting.
The answer is that the brain cannot process word "of". Do you think it is incredible or what? Now go back and look again! The truth is that anyone who counts all the F's on the first go, must be a true genius :) If you're first answer was three, that is quite normal, if your answer was four that's quite rare. If you found this amuzing, send it to your friends. It will drive them crazy.
And keep them occupied for several minutes!
Brain is a Genius... Isn't it?
"Acocdrnig to an elgnsih unviesitry sutdy the oredr of letetrs in a wrod dosen't mttaer, the olny thnig thta's iopmrantt is that the frsit and lsat ltteer of eevry word is in the crcreot ptoision. The rset can be jmbueld and one is stlil able to raed the txet wiohtut dclftfuiiy."
Now read this text again, paying attention to each word and you'll probably notice "some" typing errors ;)
