Why Do Some Farts Smell So Bad?

In 2001, Australian scientists explored whether farting in sterile environments could cause infections. Farts, primarily composed of odorless gases like nitrogen and hydrogen, are mostly harmless. The unpleasant smell comes from sulfur compounds such as hydrogen sulfide, methanethiol, and dimethyl sulfide. These compounds are influenced by diet, with foods like cabbage and eggs increasing sulfurous gas production. Fortunately, farts are not infectious when passed through clothing, posing no real danger.
