    six. the rea­son peo­ple were meant to count less is because our minds aren’t sup­posed to trans­late the F’s in the word OF

  5. Nicky says:

    I found 6 first try and actu­ally when I ini­tially started count­ing I glossed over the of but then stopped, went back and included the of’s in the count THEN read the expla­na­tion and had a chuckle. Quite the lit­tle men­tal trick!

    It is never good to com­pli­cate a sim­ple thing. How about we change the intro to say,… “read aloud, the words you see below.“
    “Finished files are the result of years of sci­en­tific study com­bined with the expe­ri­ence of years”… Then ask how many times the let­ter after the let­ter E in the eng­lish alpha­bet is used in what you just said?

    Hello from the Bahamas.
    There are 6 f’s in the sen­tence. It’s basi­cally here to say that the human brain doesn’t take in the word “of” as a word with f because it is said as “ov”.
