@@aleksitjvladica. I don't think I've ever seen "wholesome" rudely so yes, it is in fact a nice word. It's similar in meaning to what we would call "heartwarming" and (at least how I have seen and used it) is used to somehow convey that a situation gives a feeling of "emotional fullness" or something similar. At least that's how most of the stuff I have and have seen called "wholesome" made me feel.

Seems like its mostly effective during pregnancy. Normally when random cells show up in your body, your immune system destroys them. The immune system of pregnant women is compromised specifically so that their immune system doesn't destroy the fetal cells growing in them. Once in post-partum though, the immune system gets back to normal, and destroys any foreign cells left behind *usually*. The instances of them surviving are rare, and the liver is a bit of a special organ in that it naturally can regenerate anyways. It's certainly promising, but there's alot to consider risk wise. What if when you go off the immunesuppressants, some number of peoples bodies recognize the foreign cells and destroy their shiny new organ

[@tonywebert8326]

Thought Experiment: Chimerism occurs when a person has 2 genomes. This can happen when a *fraternal* twin is absorbed by the other in the womb. *Identical* twins have the same DNA (hence identical). Could it be possible for an identical twin to absorb the other in the womb? They would carry their twin's DNA, but they would only have 1 genome.

Well, identical twins happen in the first place because one embryo split into two. It then comes down to how far along in an embryo's development before you think it's a person.

The animation in this video was beautiful. Amazing job Murilo Jardim and Luisa Copetti

[@simranmalhotra7364]

It's amazing to think this way- a female who was never born, has her own children, genetically.... whoa... That would mean scientifically you can have children WITHOUT even being born!!!!

[@throughtheblackholetotheli6147]

Uhm,but thinking about,we are multicellular....this means we are just a big net of cells....so...tendentially,she did born,exactly 'cause her scattered cells are living inside the net we call "her born sister",technically they are both born,simply one of the two,got a bigger number of cells in the net of the organism.

[@KnuttyEntertainment]

That means it’s technically possible for both of your biological parents to be your aunt and uncle. Or in the case of re-absorbing your child’s cells, it’s technically not impossible to be the child of your unborn older sibling.

Yes I do have a ghost twin actually she died in the womb and I've been watched over by her my entire life. yesterday I asked her if she could hold and squeeze my hand and I felt it it was so comforting to know that she listens to me because 4 months ago she threw my phone down the hallway and I asked her to not throw my phone again I'd prefer it if she chose the items that are not breakable since then she hasn't thrown stuff as hard as she did with my phone and they've all been non-breakable items. I used to see her as a child all the time and talk about the girl who looks like me at that age my mum hadn't told me about my twin and now I only occasionally see her for a split second out the corner of my eye but she's always there for me

this sounds weird but interesting

[@nyx9950]

bro that's scary;-;

Learned of the this while researching tumors. Wonder why the tumors connection's not mentioned here. It's fascinating.

[@themariannelm]

There’s an episode on House called Cane and Abel that covers this - super fascinating!

[@ihopemorepeace1]

I was a little spooked when I saw this because my twin wasn't born. I used to tell everyone when I was a kid but it was dismissed as a joke and I only remembered it recently. My therapist said it was actually common and that sometimes the twin who was born mourns the absence of the other, which is my case. I thought this video was going to talk about that and felt a little scared but now I see it mentioned this in a more scientific take. It was interesting to know. I hope I have something of my sibling to carry along with me, even if it's a single cell.

So that's why I had an imaginary friend back in my childhood. I haven't even able able to read back then, and suddenly spitted out a person name which my parent don't even recognize, and even playin with him.. damn I wish I could remember more about my childhood

[@Sammy052]

The possibility of this makes me think I'm not alone. I was never alone. Thank you for sharing this info

[@aeltayeb]

Mind blowing 🤯 Animation is spot on well done!

So Dwight was telling the truth

Imagine one day we can just "activate" stem cells within ourselves to repair damaged cells.

[@nicosoftnt]

1:55 That's literally a rejuvenation process, so it is possible after all

[@pillow3588]

It’s so cool because you can look at one of her sons and they look like what her sister could’ve looked like.

[@Denuhm]

I had the same experience as Keegan's sons, I'm my 'aunts' son ^^' we found this out after my mother had a hysterectomy and they found part of the 'twin'. We later confirmed it through 23&me x)

[@chelseazaydaraensehon1198]

😱🤯 that’s crazy! If I take the 23&me test will I be able to find out if I have this?

[@Denuhm]

@@chelseazaydaraensehon1198 It's extremely rare to my understanding that a twin like my mother's affects the reproductive system specifically, we only knew what was going on because of my mother's underlying health issues and the 'twin' being found and removed and then later when our family genetic tests came back a little wonky and talking to a geneticist to confirm. You will only have this outcome IF your mother had a twin that died in utero at a later stage and it became incoprporated with her body and reproductive system to some degree.

What if a person who's a chimera commits a murder, gets caught but the DNA left by his skin/hair doesn't match the samples taken of his blood or saliva? Then authorities have no choice but to let him go 😳😱

[@feathero3]

Could this affect your mind at all? Such as both liking and disliking something, being extremely indecisive, or simply feeling like two people in one?

[@jaygibby4210]

Very simply put. Thanks
