The poop smell theory is one I stumbled upon recently and hopefully I can find more evidence or perform more research to make this more then a theory.
smelled encountered this conundrum after I went to college and my parents built a new home. I noticed that every time I pooped at my parents the smell had a different tang to it. Over the years I attributed this to my mothers cooking. But after visiting once a month for several years, each time usually dropping one deuce, I noticed that these poops were extremely pungent. The stench would travel down the stairs and hit some unsuspecting family member like a wave of death.
I finally came to the conclusion that my shit stank far worse at my parents home then at my house. I believed this lie until a few months back when I moved to a new office building. Every time I dropped the kids off I felt like I was covered in a foul film of filth (or an F3). After taking a deeper whiff of the bathroom one early morning I found that it had certain underlying smell to it before it had been cursed with 300 random men shits. Almost as if it was the tip of the iceberg just waiting to breach the water surface.
After talking this over with some colleagues the light bulb finally went off in my head. Your poop smell is directly correlated with where you poop and the main factor maybe the water being used in the toilet. Some facilities do not seem to have this attached smell accelerant; for example my second floor bathroom seems to have no hint of the after flavor. My 3rd floor bathroom however does have something going on even if it is mild.
Some proponents of this theory claim that it’s all about what you eat. After looking back on my several years experience of using the same facilities I can say with confidence that this is incorrect. Food may change some of the flavor but that underlying tang still exists. However, if I can obtain some funding I would gladly test this out by eating the same food for one week at two separate locations to try and determine the validity of my theory.
In closing, next time you find yourself in a new location give it a good sniff and see if it doesn’t smell like your normal brew. Take a walk in some fresh air afterward to see if you can still smell that pongient stench in your clothes. If you find this happening in different locations than you are most likely encountering PST.
