Digestion in the Stomach by Howard F. Loomis Jr., D.C. Digestion begins in the mouth.

When you eat raw food, its enzymes work with the salivary amylase to begin digestion.
The U.S. Owes China $1.2 Trillion. China holds about $1.2 trillion in U.S. government debt, according to the Treasury Department's latest figures. That's about 30 percent higher than the previous estimate. This is part of those global imbalances we keep talking about.
$6.2 trillion or approximately 47% of the debt held by the public was owned by foreign investors, the largest of which were the People's Republic of China and Japan at about $1.3 trillion and $1.2 trillion respectively for the two countries. The national debt equates to $44,900 per person U.S. population, or $91,500 per member of the U.S. working population, as of December 2010. 2  In 2008, $242 billion was spent on interest payments servicing the debt, out of a total tax revenue of $2.5 trillion, or 9.6%.
