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.

I bet elementary teachers would be good too

Retired Elementary school teacher here. You are correct. After the first two years and horrible flu symptoms I was invulnerable for the next twenty. Also agree on preschool teachers being almost immortal.

[–] starlinguk@lemmy.world 10 points 2 days ago (1 children)

Shame Covid doesn't work like that. You just get it 5 times a year because it's a different strain, you didn't become immune last time or you lost immunity after a couple of months. Minus 2 IQ points (on average) every time.

And even the "normal" viruses like flu can cause problems for years.

[–] moshankey@lemmy.world 15 points 2 days ago

I totally lucked out. I retired about two years before Covid hit. At my age and in that environment I would not have made it. Still dealing with the effects of having caught it all by myself. I just can’t afford to lose anymore IQ points. I’m struggling as it is.

And yet, despite education teachers everywhere refuse to mask.

At least one of us is still wearing a p100 respirator every day...

[–] Brunbrun6766@lemmy.world 8 points 1 day ago

Any teacher. When I was training for 7-12 that was one of the first things they talked about was health and get ready to get sick all the time

[–] albbi@piefed.ca 10 points 2 days ago (1 children)

They'd be alright, but preschool or daycare workers would be the gold mine.

[–] Windex007@lemmy.world 4 points 1 day ago

I'd even be interested in a parent of a 5 year old who's been at daycare for 4 years.

It's my suspicion that a second, later-in-life battering of a person with respiratory illnesses is in some part responsible for the longer average lifespan of parents. I expect the effect would be more pronounced if somehow parenting didn't come with all the anxiety and stress, which I expect is a negative pressure on average lifespan.

Yeah, I taught elementary school for 22 years. Five sick days in all that time. I'm guessing my antibodies were going full bore the whole time.

[–] DarrinBrunner@lemmy.world 19 points 2 days ago (1 children)

Before my kid started kindergarten, I "never got sick". Then it was one damn thing after another for the next three years. I wonder whether people who never have kids and never experience that are somehow worse off in old age because of it. Or, maybe better off?

The last time I was sick was Covid, and yes, my by-then adult son gave it to me, because of course he did.

[–] axexrx@lemmy.world 6 points 1 day ago

I used to be a never gets sick person. Worked in restaurants in a resort area, so I was constantly exposed to germs from all over the world.

Even my constant exposure to the school germ breading grounds via best friends kids never got me sick.

I made it through covid with only 2 positive tests, both while completely asymptomatic, and both times being clear after 48 hours. And I was serrious about it because I was living with an elderly parent.

At one point, early on, I shared a wine glass with the owner of the restaurant, not just once, 2-3 hours of sharing a cup. A couple days later, it turned out she had gotten covid from her BF. I never got it off od her.

Then I left the restaurant industry. Within 3 months, my immune system normalized, and I was catching colds of my my friends kids, nights out at packed bars, etc.

[–] ProfessorScience@lemmy.world 19 points 2 days ago (2 children)

That is kind of cool, I guess, but it kinda feels like "Let's take these valuable care providers and take advantage of the increased exposure to germs that they subject themselves to, and then HARVEST THEIR VERY BLOOD!"

[–] Viking_Hippie@lemmy.dbzer0.com 16 points 2 days ago

You've got a point, but the Venn diagram of people who would become a pediatrician and people who voluntarily give blood is likely as close to a circle as most professions get anyway, so this is just smart use of a resource provided willingly 🤷

[–] batmaniam@lemmy.world 2 points 1 day ago

Looks like they screened it and then were able to reproduce the relevant antibodies in vitro.
