While searching for a kidney donor, Karen Keegan stumbled upon a mystery. After undergoing genetic testing, it turned out that some of her cells had a completely different set of genes from the others. And this second set of genes belonged to her twin sister- who had never been born. How did this happen? Kayla Mandel Sheets explores the condition known as chimerism.

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.

    • My little brother, he absorbed his twin and gained a chromosome and lost chromosomes in some other things. It caused his organs to not fully develop. He was missing a lot of the vital organs. He’s organs were also flipped. He didn’t make it because he was missing those vital organs. But it was astonishing how much time we had with him. He also had extra fingers and toes. My mom got little plasters made of his little arms and legs and he had like an extra thumb and pinky toe 😆

There is knowledge in light and within you that only you can understand. . It's like deja vu You've seen yourself somewhere you don't know when or where until it snaps and it's gone. . Light particles follow a rhythm/pattern until observed too closely. . With that logic. If u don't pay too much attention you can set of neurons in a way that seems like a premonition. You are here and then, but are u now? Or there.

    • 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

In fact, I asked my mother "Was I a twin during the first terms of the pregnancy?" And considering she didn't know anything about a twin, I might need to do some investigation! :D

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.

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.
