No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question 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.

Questions 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 META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, 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.



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. This includes using AI responses and summaries.

It's a fact that the rectum can absorb some amount of nutrients.

So, a person should probably be able to live for quite some time while only absorbing nutrients via enema, right?

Can it be done?

Alternatively, is it possible to survive by eating only ass?

[–] T00l_shed@lemmy.world 2 points 6 days ago

Cuttlefish and asparagus, or vanilla bean paste?

[–] SaveTheTuaHawk@lemmy.ca 74 points 1 week ago (3 children)

No, medically speaking, this is how you get Assburgers Syndrome.

[–] MycelialMass@lemmy.world 3 points 6 days ago

A loud 'HA' literally burst out of me involuntarily.

[–] EponymousBosh@awful.systems 16 points 1 week ago

Boooooooo.

But what if you stick to pasta?

[–] Breezy@lemmy.world 2 points 6 days ago

Only if its nice and al dente.

Something new to try for Thanksgiving:

Martha Stewart

[–] clay_pidgin@sh.itjust.works 4 points 6 days ago (1 children)

That's horrific. Is that Martha Stewart?

[–] dickalan@lemmy.world 6 points 6 days ago* (last edited 6 days ago) (1 children)

Yes it’s from the how to eat with your butt Southpark

[–] Hobbes_Dent@lemmy.world 35 points 1 week ago (1 children)

From Wikipedia:

A variety of different mixes have been used for nutrient enemas throughout history. A paper published in Nature in 1926 stated that because the rectum and lower digestive tractlack digestive enzymes, it is likely that only the end-products of normal digestion such as sugarsamino acidssalt and alcohol, will be absorbed.[8]

Plus I think you’d have no lipid absorption, so you could probably survive longer than starvation, but I’m guessing not “quite some” time.

[–] asdfranger@lemmynsfw.com 26 points 1 week ago (2 children)

Damn, that is tragic.

I suppose one could decide to consume ass-absorbable nutrients only by enema, and supplement the incompatible nutrients orally. That won't be pure ass, but half a loaf is better than no bread.

[–] corsicanguppy@lemmy.ca 8 points 6 days ago

That won't be pure ass

So, half-assed, you say?

[–] mbp@lemmy.sdf.org 16 points 1 week ago

Just here to appreciate your linguistic prose.

[–] CallMeAnAI@lemmy.world 28 points 1 week ago (1 children)

I feel like there is a limit on "no stupid questions", and you flew past it at 100mph with that latin music drive-by meme.

[–] asdfranger@lemmynsfw.com 8 points 1 week ago (1 children)

Latin music drive-by meme? I tried looking for it but didn't find anything resembling that.

Also, there should be no limit to stupidity ;)

[–] CallMeAnAI@lemmy.world 5 points 1 week ago (1 children)

Latin might not have been the best descriptor, and this one is dumb https://www.tiktok.com/@meg__legs/video/7229005319286885675

[–] asdfranger@lemmynsfw.com 8 points 1 week ago (1 children)

🤣 I don't think I'd be able to come up with a better descriptor either.

(same video here for those who understandably don't want to open tiktok)

[–] Son_of_Macha@lemmy.cafe 23 points 1 week ago

No. Your stomach and small intestine absorb most of the nutrients, your large intestine absorbs mostly water.

[–] vala@lemmy.dbzer0.com 21 points 1 week ago

Yes.

For how long? Science doesn't know yet.

We can finally put a number on it when Musk passes.

[–] thann@lemmy.dbzer0.com 16 points 1 week ago (1 children)

Most people survive only talking out their ass, so I dont see why not

[–] MajorMajormajormajor@lemmy.ca 22 points 1 week ago

You shouldn't make fun of a serious medical condition.

[–] Kolanaki@pawb.social 11 points 1 week ago* (last edited 1 week ago) (3 children)

You can breathe through your rectum, too, technically; but it's not fast enough at getting oxygen in your system to keep you from suffocating.

I am suspecting that eating food that way may have the same issue. It almost certainly would not break up normal food enough without saliva, chewing, and stomach acids, limiting thr nutrients you can absorb, too.

[–] BurgerBaron@piefed.social 3 points 6 days ago

TIL. Apparently there were studies done using an oxygen-enriched enema potentially for drowned people to resuscitate them. Didn't work lol.

[–] asdfranger@lemmynsfw.com 5 points 1 week ago

I'm not thinking about actual undigested food, but special food "slurry", with nutrients specifically arranged and concentrated for maximum absorption.

[–] dysprosium@lemmy.dbzer0.com 3 points 1 week ago (1 children)

But your rectum does not absorb any oxygen

[–] Kolanaki@pawb.social 1 points 6 days ago

Look up the term "enteral ventilation via anus."

[–] elevenbones@sh.itjust.works 3 points 1 week ago

Oh fuck, I've been eating wrong this whole time

[–] Drbreen@sh.itjust.works 1 points 1 week ago

If we could eat through our arse, we'd all be living forever.
