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.
A commodity generally refers to an agricultural product that is bought and sold such as corn, coffee, wheat, etc. Energy commodities include gas, electricity, oil, etc.
Commodity has a special meaning as a raw product that is generally the same from one batch or producer to the next. While you can can buy a pound of a particular brand of pinto beans from the grocery store, pinto beans are traded in the stock market in much larger quantities based on a commodities price.ommodities are something used to make goods. And goods go to the end users. For instance, flour is commodity and bread is goods. If I tell you in a very informal way then commodity is a species of molecule/grain or whatever. Whether you buy wheat from place A or B, wheat is wheat.
