What is it: (Courtesy of Wiki)
Flatulence is defined in the medical literature as "flatus expelled through the anus or the "quality or state of being flatulent" which is defined in turn as "marked by or affected with gases generated in the intestine or stomach; likely to cause digestive flatulence" The root of these words is from the Latin flatus – "a blowing, a breaking wind" Flatus is also the medical word for gas generated in the stomach or bowels These standard definitions do not reflect the fact that a proportion of intestinal gas may be composed of swallowed environmental air, and hence flatus is not totally generated in the stomach or bowels. The scientific study of this area of medicine is termed flatology.
Some basic facts about farting:
The average human farts 14 times a day. (I guess I am nowhere near average in this respect, 14 times before I leave for work in the morning)
You fart enough to fill a balloon each day! Woah!
Each fart travels at about 7 miles per hour. That’s pretty fast!
Only 1% of each fart smells bad at all. The other part has no odour!
