    Got all of them right. This was pre high school information back in the dark ages when I learned it. [If you are curious about just when those dark ages were, do the math. I was in one of the first groups of elementary school kids to receive the Salk Polio Vaccine. I suppose this might qualify me as, "crusty," had I not been known to bathe regularly.] Newsflash! Students are STILL being intensively exposed to this information in upper elementary. Well...at least in the schools in those allegedly 'inferior' southern states where I was educated and still reside. Actually, the state & locally developed science 'common core' curriculums in these states are teaching more advanced physical science concepts than this at middle school levels It's not the quality of the curriculum anymore; it's the quality and motivational level of the students. Too many of them don't understand the concept of serious study, and teachers are kept too busy confiscating the high tech gadgets that serve as both their memory and entertainment. It's like the old saying goes with respect to learning anything, "First you have to give a shit."

    Thanks! coconut oil is an easy find here and I have the rest. Some altoid tablets and some real lemons. The stevia comes amazon in 1000 packets to a box size.

    "the more sugar people eat, the more likely they are to get cavities."
    This statement, in my reading, implies if members of the same cohort changed no variables other than sugar consumption, it would change their rate of cavities. This means causal correlation.

    Hey Michael!

    Try this...
    1) Four or five heaping tablespoons of cocoanut oil
    2) one teaspoon baking soda
    3) Stevia to taste
    4) a few drops of peppermint extract to taste
    5) a few drops of lemon extract to taste

    Mix the whole mess together and brush twice daily. I've been using this for a year or so now, no cavities and my teeth have never felt cleaner. The bonus is no fluoride!

    Every time I go to a dentist I'm told to brush a different way. After many decades I gave up and brush about six times a day using all techniques. But since I got a folding toothbrush and copied the lead of Jack Reacher not a single problem. I didn't know about citrus i do a grapefruit and two oranges a day. Down here we get the real cane sugar but i switched to stevia.

    Seriously, six times a day and for sure after eating is not too excessive. Followed by a good mouth wash. As the others said it's 'germs and bacteria.'

    And a new toothbrush

    some of the questions in the poly science test were pure guesswork. I didn't find that to be true in this science test although i still think distance was a better answer to the speed of light question. As for the volume of sound wasn't it Planck that pointed out sound gets louder as it 's closer and loses volume as it grows more distant due to sound waves ? I'm open to improvement though. I'll have to re read that section. Maybe I just descrived amplitude without knowing i had done so. Or maybe I just don't know from nuttin!

    two wrong. I tried the political status one and found the answers were apples and oranges not either or. But the science one was very good and well worth the time.

    I have always been a literary-type which I suppose is why my favorite kind of humor is puns.

    A few jokes kinda do have a quirky sense to them.
    A couple of years ago I read that the essence of humor is the unexpected.
    "Now take my wife--please!" is only funny the first time you hear it combined with the set-up beforehand.

    Real sugar kane was not quite the villain it was touted to be, although, sugar, real, processed, fake or from corn is not good for any of us, especially non-secretors. Cavities are usually caused by germs and germs LOOOOOVE sugar. Excess Citrus is also bad for your teeth but is not fully responsible for cavities either.
    All this stuff, I founded out waaaaay to late in life.
    Oh well...

    Thank you for the links. I will do some research, but I have to disagree with your statement that sugar has little to do with cavities, although I agree it is only one factor.

    That is the saddest thing that can be said about the state of today's education. Without reading comprehension, most of them are doomed to a 2nd class life, or worse.

    Most jokes make no sense when you really think about them. That's what makes them funny.

    Someone's vulnerability to cavities depends primarily on secreator status; def. if every fluid in the body not just your blood expresses your blood type antigens then you are a secreter and less vulnerable to cavities, but might also react adversely to viruses more easily. Non secretors...just the opposite, most, no matter what you do, you get cavities. Yes, your immune system battles tooth decay if it is expressed in saliva.

    I'm black and Jewish, so I either split myself in two, or I decide that intelligence is individual.

    Your PV remark was precious. Since I've been in both science and economics, I have to make sure what I'm talking about.
