Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

How are fats, oils, and grease getting into the sewer system, though? Are there enough of those materials left in our poop to conglomerate like that? Or are those from industrial users on the sewer system?
Lots of restaurants and cafes pouring their waste cooking oil down the sink instead of paying a collection service.
That seems like a great way to plug your own drains.
Also, I was under the impression that restaurants could sell their frying oil for recycling? This is a weakly held impression to be sure but I want to remember reading something about it.
From doing dishes and stuff like that.
They come from your sink, not your toilet
Man, I'm an idiot. I dunno why I forgot for a moment that other drains exist lol. That makes sense, thanks!
Maybe you have a drain phobia? Mr. Rogers had a song one day on his show called "you can never go down the drain" which was supposed to stop kids who were scared of that happening... but until he sang that song, the concept of me going down a drain was not something I had considered, so I was terrified of it for years and had to jump out of the bath the minute my mom pulled the plug.
On the other hand, you're probably not as weird as I am, so you probably just forgot.
Huh, I know I used to watch Mr Rogers when I was real little, but I have few memories from that far back. But I also, to this day, get uncomfortable putting my fingers or toes near drains.
I need to hear this song. Maybe it'll trigger some latent memory and unlock some long-forgotten trauma.
Edit: Found it, no memories unlocked. :(
