      It smells because of the bacteria that live on and in you! Different gases smell different, and the bacteria that live on you can sometimes produce the smelliest ones, like sulphur dioxide.

      Some gases smell because of the compounds within them including the ones that humans produce. Most unpleasant gas smells are because they contain sulfur-containing compounds which smells like rotten eggs 👃
