The coral reefs existing today began growing as early as 50 million years ago. Most established coral reefs are between 5,000 and 10,000 years old. Although size can be a good indicator of the age of a coral reef, it is not a certain indicator.he coral reefs existing today began growing as early as 50 million years ago.

Excessive flatulence is generally caused by bacteria that live in the intestines. Another, less common, cause is the swallowing of excessive air. Intestinal bacteria produce different amounts of gas depending on what you eat. Sugars and polysaccharides tend to yield flatulence. If excessive flatulence is a problem, adjusting your diet can make a big difference.
Flatulence usually only has a bad smell if it contains gases that smell, such as sulphur. However, it's important to remember it's normal for the gas you pass to sometimes smell a bit. Excessive flatulence can be caused by swallowing more air than usual or eating food that's difficult to digest.latulence usually only has a bad smell if it contains gases that smell, such as sulphur.
