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.

Today I learned that snot turns yellowy greenish for the same reason that pee turns yellow, dehydration. The snot usually isnt yellow other than when we are sick because usually we don't have a runny nose while dehydrated except specifically when we are sick.

And also once again, humidifiers save the day because they both tackle the dehydration by putting moisture into your airways and the nature of water in the air helps break up stuff that is stuck anywhere in your airways by lubing it up and making it take its course faster while also freeing up bandwidth for your body to continue shoving more of the sickness out of your body faster which helps you recover sooner.

I know I’m getting sick when my boogers smell like peanut butter.

No idea why, but a couple days after I notice this I will have a sinus infection.

Did you put peanut butter in your nostril? That would explain both things you experience.

Don't bring cigarettes into this! I have it on good authority they can be restorative.

This isn't as crazy as it sounds

It was used as a delivery system for inhalable medication back when they didn't have vaporizers/etc
