Back in April, Daniel Gross ended a column predicting that President George Bush would be unable to find a top Wall Streeter to fill the Treasury secretary position with the promise to eat the first chapter of Dow 36,000 if he was wrong. Now that Hank Paulson has been nominated, Gross has done the right thing. Slate actually posted a video of the paper meal.
According to Everything.2Com:
Paper eating is a form of the eating disorder Pica. People with Pica tend to crave non-food items, such as paper, clay or dirt. Pica is often caused by iron-deficiency anemia.
The chemicals used on paper and the ink on the paper are not safe for human consumption. It is known that you can get mercury poisoning from eating paper.
