    Fun fact, humans actually produce only trace amounts on methane in our farts because we’re not ruminants. Most of our farts are nitrogen swallowed from the air and CO2 produced by gut bacteria. The bad smelling chemicals are in even lower concentrations and barely make up a rounding error by volume, we simply evolved to be really sensitive to them because it’s beneficial to our survival to avoid poop.
