A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

I really doesn’t matter tho because poop particles are everywhere regardless of your toilet seat orientation.

While true, quantity of poop particles also matters.
Your body can fight off loads of bacteria. But once it gets to an infection point, it can't keep up and you become ill.

So yeh, poop is everywhere. As long as it's small amounts, it's fine.

The study where gustofwind got the illustration says it's around 10x reduction of deposited bacteria with the lid down.

10x reduction doesn’t even make sense. It’s not possible to reduce by more than 1x, as that would be 100% of the bacteria gone.

And your link doesn’t support what you said at all.

The floor and the walls of the restroom were contaminated after toilet flushing, but no significant differences were observed between the contamination occurring with lid position up or down. Wall contamination was minimal, regardless of lid position, and there was no significant difference in contamination level between the surfaces assessed, but data indicated that the trajectory of the aerosol plume contamination may have changed. Floor contamination was not found to be reduced consistently by toilet lid closure prior to flushing.

Am I misreading something?

I'm not interested in their narrative, I'm talking about their numbers. They measured plaque formation - colonies - of bacteria from surface wipes around the toilet after flushing a contaminated toilet bowl. Depending on the location & lid state, they got, generally 10^3-10^6 plaques. 10^5 with the lid closed, 10^6 open, which is a 10x difference. There's no difference in the surfaces directly facing the bowl; hardly surprising that there's little contamination left by the time you get all the way to the walls - 1/r^2 effect. Look at the surface you sit on.

I’m much more interested in the conclusions and the meaning of the numbers, for two big reasons:

  • It doesn’t matter much if the reduction is 90%, if the remaining 10% is still enough to be a problem. It sounds like a lot, but I have some doubts that it actually makes much difference.
  • I care a lot more about locations outside the toilet than the specific locations in and on the toilet. The toilet is assumed to be contaminated regardless, the question is whether or how much it is contaminating the rest of the room.
[–] FishFace@piefed.social 1 points 4 hours ago

But how does it compare to what's already there? How does it affect the average toilet user's bacterial load, and how does that compare to an approximate threshold for infection?

House dust is up to 50% human skin particles. You're breathing in all sorts of crap, and outside I'm sure there's loads more including animal crap.

It’s a lot easier to clean the walls than the ceiling

☝️🤓

[–] athatet@lemmy.zip 1 points 1 hour ago

Clean both. Don’t clean both.

Still. The poop particles remain.

[–] FishFace@piefed.social 1 points 4 hours ago

But I don't lick the ceiling...
