A hiatal hernia occurs when the upper part of your stomach pushes up through your diaphragm and into your chest region. The diaphragm is a large muscle that lies between your abdomen and chest. You use this muscle to help you breathe. Normally, your stomach is below the diaphragm, but in people with a hiatal hernia, a portion of the stomach pushes up through the muscle. The opening it moves through is called a hiatus. This condition mostly occurs in people who are over 50 years old.

Definition of Commodity Money. Money is a type of asset in an economy that is used to buy goods and services from other people. A commodity is a physical item that is readily interchangeable with another item of the same type. Commodity money is a commodity that has intrinsic value. Intrinsic value means that the commodity has value even if it is not used as money. In times of economic turmoil, such as severe economic depressions or hyperinflation, people sometimes turn to commodity money instead of the money authorized by their governments.
