Air expelled from the anus. It can be silent or very noisy, depending on sphincter's tension, speed and amount of gas expelled. Farts can be stinky or inodor, and some kinds of food (like beans, rice, pasta and generally all foods containing high amounts of carbohydrates) cause more gas production. We all fart about ten times per day. Farting is a natural and healthy body function.
