Read the sentence below carefully and count the number of F’s:

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

Did you find all six F’s? If not, don’t be surprised. Only 15 percent of people do. If you counted less than six - most count three - you probably missed the ‘f’ in each “of”. Since ‘of’ is pronounced ‘ov’, the verbal left brain hemisphere took the verbal clue and overrode the right, ‘seeing’ brain hemisphere, forcing the wrong conclusion.

Your imagination and understanding of what you see is the finest case of mind over matter...
