I guess it makes sense, but I've never thought of it like that before.

It is a lint factory.

[–] Quilotoa@lemmy.ca 16 points 10 hours ago (1 children)

And unique to each individual. Perhaps we can use it as a security identifier along with fingerprints.

[–] IAmNorRealTakeYourMeds@lemmy.world 18 points 9 hours ago (2 children)

bellybutton ID to replace faceid, soon all business wear will have exposed belly button.

That's normal office attire

[–] bhamlin@lemmy.world 5 points 6 hours ago

We can call it NavelGazr

[–] Skyrmir@lemmy.world 5 points 8 hours ago (1 children)

Nay they'd be covered with a flap, can't have people taking pictures to fool security with, but you need to easily expose it for check points.

Fine, people can wear belly button stickers, like nipple covers

[–] BeMoreCareful@lemmy.world 17 points 11 hours ago (2 children)

For a long time I believed that my belly button grew hair. As my belly button had a little tuft since puberty. I mean there were new hairs then, so I just didn't consider it.

One day the conversation (exposed navels were in vogue at the time) turns to this little tidbit.

Well, you can imagine me putting two and two together and eventually tugging a little plug of dead skin and belly button lint wrapped around a few dozen hairs.

I wish it hadn't been before smart phones. It was one of those things that's so gross you hang onto it for a day or two out of some primordial reverence.

Also, does anyone else's navel serve as a nausea button? I've had several partners try to play with it and it's not enjoyable at all.

[–] johnyreeferseed@lemmy.dbzer0.com 3 points 7 hours ago (1 children)

If my wife sticks her finger in my belly button it makes my butthole tickle. I don't enjoy it but I can see how others would lol.

[–] diabetic_porcupine@lemmy.world 2 points 6 hours ago

It’s not the tickle it’s the stretch

[–] colourlessidea@sopuli.xyz 14 points 11 hours ago (2 children)

+1 to nausea button! Anyone know why that is?

[–] Uranhjort@lemmy.world 2 points 3 hours ago

Well for one thing your guts are like right there behind it, they don't much like being poked.

my guess is because it's a vulnerable area (lots of soft tissue directly behind it) and so it makes sense that your body says "ugh, no" when something touches it.

[–] Tollana1234567@lemmy.today 25 points 15 hours ago (1 children)

people who had the rare appendicial cancer, have to get thier bellybutton(among other organs) removed, because the "cancer jelly spreads all inside the abdomen whent he cysts burst. audrey hepburn had this disease.

[–] Spacehooks@reddthat.com 10 points 14 hours ago

Do they like have a smooth belly like clones in space: above and beyond?

[–] FinjaminPoach@lemmy.world 38 points 17 hours ago (9 children)

A show i watched as a kid was a Dr Who Spinoff called The Sarah Jane Adventures and a main character is a faux-human created by aliens in a lab, who therefore has no belly button. I've always thought that was really interesting and that it's unfair we can't have smooth, holeless abdomens too.

[–] toynbee@piefed.social 4 points 4 hours ago

Apparently, when plastic surgeons do tummy tucks, they sometimes have to "drill" out a new navel.

[–] quick_snail@feddit.nl 2 points 7 hours ago

Seems like a reasonable place to attach the electrodes tho

[–] gandalf_der_12te@discuss.tchncs.de 11 points 12 hours ago* (last edited 12 hours ago) (1 children)

eh, if aliens ever produce lab-grown humans, i think there's a 99.9% chance they'll have belly buttons too, guessing that they're growing them in artificial wombs where the baby makes an umbilical cord.

i mean why would you do it any other way? maybe an infusion directly into the arm or sth ...

[–] Swedneck@discuss.tchncs.de 1 points 8 hours ago (1 children)

right? the umbilical system is frankly so useful and well designed that it's one of the few things you can't use as evidence against god creating us. It actually looks like some thought was put into the design.

lots and lots of biological systems are very well made

[–] Murse@slrpnk.net 25 points 16 hours ago (3 children)

unfair we can’t have smooth, holeless abdomens too.

Gonna throw this upfront: Don't image search this unless you're prepared to see some seriously mutilated babies on the brink of, or in some cases shortly after their death. This is close to the top of the worst NSFL shit on the internet.

Anyway, gastroschesis. Birth defect in which the intestines are outside of the body at birth. The fix is to basically cut a new hole and shove them back in, with the resulting wound being kinda at the doctor's / parent's discretion: they can immitate a natural belly button, or just say fuck it and give it a clean closure line, the resulting scar from which can heal with virtually no visible scar tissue. I think it's more common for there to be -some- disfigurement from the scarring, but babies have fucking super powers when it comes to healing, and a wound that would give you or me a ropy, nasty scar, would look like a little scratch on them.

So, not quite smooth/holeless in the way you're probably thinking, but potentially not far off from it - all you need to do is be born with a condition that's likely to kill you!

[–] shoe@feddit.uk 1 points 6 hours ago

My niece had this! Her parents elected to leave her without a belly button and, yep, no visible scar tissue :). Pretty incredible, given how dire things looked when she was born.

[–] FinjaminPoach@lemmy.world 4 points 9 hours ago

Thank you for the nsfl warning, I will NOT be googling that. Interesting to read though.

[–] lb_o@lemmy.world 17 points 14 hours ago* (last edited 14 hours ago) (1 children)

On the bright side - 95% survival rate.

Thanks for sharing, was a strange read, but made me fear less essentially.

[–] Murse@slrpnk.net 4 points 8 hours ago

95% survival rate

Oh, I had no idea it was that high! I had ~50% on my brain. That's pretty incredible looking at some of these - crazy portions of their abdominal contents are just hanging out.

[–] FinjaminPoach@lemmy.world 11 points 17 hours ago (1 children)

Ah, commonn sci fi trope i see. Also funny thst the wikipedia article there makes it sound like having no belly button would be as big a concern as amnesia itself

[–] Tollana1234567@lemmy.today 8 points 15 hours ago

usually indicate they are clones.

[–] Valmond@lemmy.dbzer0.com 2 points 16 hours ago

Moebius' the Incal has it too, clones of John Difool detects him as the "cloning father" because he has a belly button.

[–] lugal@sopuli.xyz 16 points 16 hours ago (2 children)

There is a religious debate in the Talmud if Adam had a belly button

[–] FinjaminPoach@lemmy.world 3 points 9 hours ago

I imagine that, if he hasn't (because shaped from clay or whatever) then it implies that the presence of a belly button in every other human is a "flaw," which is in-line with the idea of fallen creation.

That said, "made in God's image" does not mean resembling God. It means made as God's "imagers" - symbols of his power and keepers of his will. It's a concept inherent to every other early middle eastern religion; Idols of a deity, even as little statues, are exactly that. Yahweh didn't need statues because humans were his "statues".

A mistranslation, unfortunately.

[–] SeductiveTortoise@piefed.social 7 points 11 hours ago (1 children)

If Adam had one and he was made in the image of god, would that mean that god had one as well? And that god therefore had a mother?

[–] lugal@sopuli.xyz 8 points 10 hours ago (1 children)

Exactly these kinds of questions

[–] SeductiveTortoise@piefed.social 4 points 10 hours ago

If we could combine that with drinking wine or beer and playing cards, I'd be interested. Oh, and of course, don't take it seriously because that would kill all the fun.

[–] wreckedcarzz@lemmy.world 11 points 15 hours ago

smooth, holeless

I'm a barbie girl, in a barbie world...

[–] Zwuzelmaus@feddit.org 4 points 17 hours ago (2 children)

smooth, holeless

...undecorated

[–] lugal@sopuli.xyz 1 points 16 hours ago (2 children)

So you're saying your scars decorate you?

[–] Zwuzelmaus@feddit.org 2 points 15 hours ago* (last edited 14 hours ago) (1 children)

So you're saying

I do not need to correct everyone who tries to misunderstand me. Keep your wrinkled opinion if it makes you happy.

[–] lugal@sopuli.xyz 2 points 13 hours ago

I didn't mean to insult you or anything but just make a joke

[–] FinjaminPoach@lemmy.world 1 points 16 hours ago

Oh, okay yeah. Not holeless. Please not a holeless abdomen 😭

[–] some_random_nick@lemmy.world 1 points 13 hours ago

The anime's Dr. Slump main character, who is a robot girl, has the same issue. I think it was brought up just in one episode and the Dr. fixed it afterwads.

[–] West_of_West@piefed.social 14 points 18 hours ago (1 children)
[–] Spacehooks@reddthat.com 4 points 14 hours ago

Oh man thats a thought. Reminds me of claymore. The hunters have never healing scar on their bellies that never heals after they get turned into living weapons.
