Showerthoughts

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:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- 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
- Posts must be original/unique
- 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.
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:
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
☝️🤓
Clean both. Don’t clean both.
Still. The poop particles remain.
But I don't lick the ceiling...
