When people pass gas, most bystanders scatter and hold their breath, but researchers at the University of Exeter in England suggest sticking around and inhaling through the nostrils.

Scientists say savoring the noxious gas hydrogen sulfide -- a byproduct of the body's work breaking down food -- could help stave off the development of cancer.

"Although hydrogen sulfide gas is well known as a pungent, foul-smelling gas in rotten eggs and flatulence, it is naturally produced in the body and could in fact be a healthcare hero with significant implications for future therapies for a variety of diseases," said Dr. Mark Wood, a researcher at Exeter.

In a new study, Wood and his colleagues suggest small doses of hydrogen sulfide can help reverse mitochondrial damage. The mitochondria are the "powerhouse" of the body's cells, driving energy production in blood vessel cells.
