As an avid reader of all kinds of mental curiosities, a good friend sent me a few a while ago, and two of them surprised me no end. Here they are:
THE ALZHEIMER’S VISUAL TEST
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 did you find?
Wrong, it has SIX – for certain. Read it again!
How many have you found now?
Seriously, go back and try to find all SIX before moving on!
The reason for this is explained below:
The brain can’t process the word “OF”.
Incredible, isn’t it? Take another look.
Those who managed to count all SIX “F”s on the first try are geniuses.
SPINNING WOMAN

Look at this woman spinning, and if you think she’s spinning clockwise, the right side of your brain is working. If you think she’s spinning anticlockwise, it’s the left side of your brain that’s working. And if you manage to see her spinning in both directions… you’ve got an IQ of 160 or better.
Amazing, ciao, stronk7 🙂
