Week of March 13:

This weekend we moved our clocks ahead one hour to spring forward into Daylight Saving Time. Boost your brain by determining if these statements are true or false:

  1. True or False? Two US states do not observe Daylight Saving time. 
  2. True or False? Daylight Saving Time begins at the stroke of midnight on the appointed day.
  3. True or False? Farmers and department stores find great benefits in Daylight Saving Time.


  1. True – Hawaii and (parts of) Arizona do not observe Daylight Saving Time.

  2. False – Daylight Saving Time begins at 2:00 am local time – the idea is that most people will still be at home or even asleep for the night and most businesses will be closed.

  3. False – While department stores have found that more daylight is good for business because more people go shopping, farmers opposed it from the beginning because it wreaks havoc with their schedules, they have to wait for the dew to evaporate off the hay in the morning, regardless of what time it is, and it throws the cows off!

    Week of October 24th: 

    Here's a fun way to exercise different lobes of your brain.   Count the number of times the number "6" appears below.  Now count the total number of times a "3" or a "7" appears as you see them. (In other words, don’t just count all the “3“s, and then the “7“s; count both at the same time as you see either one.)  For example, the number of times a 3 or a 7 appear is this sample, "763537" is 4 times.


    The important thing here is not so much to get the right answer, but to exercise your frontal and parietal lobes by trying.

    Answers: “6” appears 33 times, and the total times the numbers “3” and “7” appear is 59 times.

    Week of October 17th: 

    Below are pairs of words, and your goal is to find a third word that is connected or associated with both words.

    Try your luck with the following words.

    1. SHIP and CARD
    2. SCHOOL and EYE
    3. PILLOW and COURT
    4. BED and PAPER
    5. Army and WATER

    Week of August 29th: 

    Gretchen and Henry were looking to buy a house together, and finally found one with a beautifully landscaped yard, plenty of bedrooms, and a beautiful tree out front. They asked the owner how old the house was, and this was his reply:

    "I planted that tree when the house was built. It was 7 feet tall at the time. It has grown 3 feet each year, and at the end of this past full year, it was four times its original height."

    "But how old is the house?" asked Henry.

    Gretchen said, "Don't be so dense. He just told us."

    So, how old is the house?


    The house is 7 years old.
    The tree height is 28 feet, since it is four times its original height.

    To figure out the age of the tree, let x = age of the tree in years. The height of the tree is then 7 + 3x. Since we know that the tree is now 28 feet, we can say:
    28 = 7 + 3x
    21 = 3x
    7 = x

    So the tree must be 7 years old, making the house just as old.

    We start with what a pen can write
    Then add an "s" for a tool of lesser might

    Change "d" to "n" for an oath professed
    Remove letter one for a condition no longer the best

    Change "w" to "t" for something forced apart
    Reverse my ends, then add an "h" for what's atop a chart

    Change "n" to "w" to learn how much an item can fetch
    Finally, anagram me for what in baseball may follow a stretch

    What did we start with?
    What do we end up with?


    Each line of this riddle is explained as follows:

    1. word - We start with - A "pen can write" a word.
    2. sword - Then add an "s" - "for a tool of lesser might" - This alludes to the adage: "The pen is mightier than the sword."
    3. sworn - Change "d" to "n" - "for an oath professed"
    4. worn - Remove letter one - "for a condition no longer the best" - If something is worn, then its condition has deteriorated.
    5. torn - Change "w" to "t" - "for something forced apart"
    6. north - Reverse my ends, then add an "h" - "for what's atop a chart" - Switch the first and last letters of "torn" giving "nort", then add an "h" giving "north". "North" (or "N" representing "North") is usually found at the top of a chart.
    7. worth - Change "n" to "w" - "to learn how much an item can fetch" - The worth, or value, of something will determine how much money it can get in exchange for it.
    8. throw - Finally, anagram me - "for what in baseball may follow a stretch" - "Throw" is an anagram of "worth". In baseball, the pitcher may throw the ball after a certain windup known as a stretch.

    The five words in the group below have something special in common.  They can be transformed into five new words by applying the same exact change to each word. What is the change and what are the resulting five new words?


    Answer:  The special thing these words have in common is that when each word is prefixed with the letter "f", the result is a new word that is completely unrelated in meaning to the original word, as follows:

    f + action becomes the word faction
    f + allow becomes the word fallow
    f + lawless becomes the word flawless
    f + lower becomes the word flower

Person A can cross the bridge in one minute, B in two minutes, C in five minutes, and D in eight minutes. When two people cross the bridge together, they must move at the slower person’s pace.
