A French doctor has urged his fellow countrymen to start letting off wind.
Frederic Saldmann says they should give free rein to break wind, burping and sweating to reduce the risk of cancer.
In his book, 'Le Grand Menage', Dr. Saldmann says the French should feel comfortable to fluctuate.
Getting rid of the two litres of gas produced each day is a "natural process" and retaining it can be harmful to the intestines.
Similarly, he says his countrymen should feel free to belch at will and certainly after each meal.
This, he says, is the best way to reduce the risk of getting a hiatal hernia, an ailment which affects almost a third of French people.
