...Fun Friendly Phobic Fact Friday!!
When someone passes gas, odor molecules and bits of fecal matter from that person's bowels are expelled into the air. How much is released depends on the filtering efficiency of their underwear and pants. Odor molecules are very tiny, so a lot of those escape into the air...and they're what causes your nose to register the bad smell. Particles of fecal matter that are very small, along with intestinal bacteria and other germs, may also make it into the air--and you breathe them in and swallow them.
You're welcome.
