What is it with Paper and Danger??

Being the mother of six young children, I am always in a state of awe and wonderment at the point that each of my children have fallen in love...in fact, become obsessed...with two things.
Paper and danger.
This has occurred with all six children at around the ages of 8 months to maybe...well, I'll have to do a future study on this one. It is like their palate has honed in on the flavor, texture, and otherwise utter blissful 'mouth-feel' of.....drumroll....paper. Yes, folks. Paper. That bland nasty white or colored stuff made out of trees that have been pulverized, chemicals added, and rolled out to a fine sheet. It ranks number one at our house in toddler dietary requirement. There is always some type of paper in Kaitlyn's mouth and she will pull on shelves, heedless of any danger (also a love of toddlers at my house) for.....paper. It's like I can read her mind..."Love paper. Must have paper." If there is paper in a fifty foot radius of her, she will do everything to get it into her mouth.
My husband always laughs...and winces...as the comics come out....well....you know.
Another thing highly desired is danger. It's like her guardian angel is checking us to be sure we are on our toes. If there is a set of stairs to climb, a shelf to pull, or a needle in a haystack...a baby will find it. Lost something small, metal, and sharp? Just put a crawling child on the floor and you will have it in mere minutes. They are like human metal deteators. And when they find it, you better be alert, because it will go right into the mouth. Amazing.
Recently, one of my other kids spilled a bunch of my mother's straight pins on the floor. All five of my children looked all over the floor (and myself and my mother) for at least half an hour to find them all. Wouldn't you know it, but every time we saw Katie, she had another we all had missed in her hands.
Mike did an experiment where he laid out a bunch of her bright and shiny toys in front of her and placed his Swiss Army Knife in there randomly (closed, of course) and sat Kate in front of the array of items. She quickly scanned the items and immediately grabbed the knife.
Scary...
Hmmm....I wonder if paper has any nutritional value......
