Interesting article Vance, I would imagine some of those "myths" started from some those "Pop" doctors we see on tv?
Now, the moon part I have a tendency to believe simply because my sun-sign is "Cancer" and I am ruled by ebbs and tides of the moon. I dare say that I would imagine those with higher incidents of acting quirky when the moon is out are mostly Cancers!
Opposites attract can also have its basis in astrology because for every sign is an opposite..often they really don't get along, however, if they're able to over come it and "compliment" each other than this "opposite" may work.
(Just an FYI I am an astrology buff.)
Both young and old alike are gullible and easily influenced by what the "authorities" say. They follow the trend. One minute you can eat butter, than you can't...then you can, but only in moderation! They lead, everyone follows. Your baby should listen to Mozart...
