There's something pretty special about the connection that twins share.

As a proud twin myself, I can vouch for the fact that we share an incredible, and somewhat indescribable, connection with our other halves. When you share a womb with someone for 9 months, it's pretty hard to not have an unbreakable bond later on in life.

And a set of twins in Ohio have now gone viral for their inseparable connection after they were photographed holding hands just moments after their birth. Too cute, I know.

And, like most identical twins out there, the sisters have remained fiercely close, and very rarely leave each others' sides.

You're doing us twins proud, girls.

Twins are quite simply mesmerizing.

As a twin myself, I think that we're pretty darn cool. But the likelihood of having twins here in the US is still quite slim, with all pregnant women having approximately the same chance of having identical twins: about 1 in 250.

As twins, we don't share your average sibling relationship. Twins and other multiples, like triplets and quadruplets, share an uncanny, somewhat absurd closeness which other people often perceive as "weird" or "strange."

Hundreds of twin studies have been conducted over the years.

The scientists who’ve run twin studies over the years have learned a lot from identical twins about what kinds of traits — from taste to personality — are genetic. But, surprisingly, they still know very little about the mysterious power of the twin bond.

Science is often the answer to this unbreakable bond.

Because identical twins come from a single fertilized egg that splits in two, they share virtually the same genetic code. Though there may be minor differences in their personalities, it is more common than not for twins to have an inseparable relationship like no other.

And some put it down to their shared upbringing.

Because twins tend to share the exact same upbringing and experience the same life experiences and learning curves at the same time as each other (first day of school, et cetera...), some researchers argue that this could explain the close relationship shared amongst twins.

Though I personally think that it's simply magic.

I don't think that anyone will ever fully crack the twin Da Vinci code, we're far too complex for that.

Though the mysterious twin bond is still very much talked about...

We're always seeing cute twin pictures online, but the remarkable story of one set of twins from Ohio went viral after a photograph of their birth was released.

Meet the Thistlethwaites.

Sarah and Bill Thistlewaite are the proud parents to son, Jackson, and twin daughters, Jenna and Jillian.

Though Jenna and Jillian didn't have the smoothest of arrivals...

Nineteen weeks into the Thistlethwaite’s pregnancy, an ultrasound confirmed that their twins were “monoamniotic," meaning they shared an amniotic sac.

“It’s the rarest form of twinning and it carries the most risk," explains Dr. Mancuso, who delivered the twins at Akron Children’s Hospital. “Because they’re sharing the same amniotic sac, their umbilical cords can become tangled as they’re growing and moving which can cut off blood supply to one or both twins."

And twins, in general, face the risk of a premature birth...

And they are more likely to be below the average birth weight, even if they are born on time.

The girls had only a fifty percent chance of survival.

Prior to their birth, Sarah was forced to spend fifty-seven days in bed to minimize any risks to the girls. Luckily, she safely delivered both girls via a cesarean section on May 9th, 2014.

Though there was something quite remarkable about their delivery...

They were holding hands.  Jenna and Jillian were born forty-five seconds apart and as soon as the doctors held them close to each other, they clasped hands, stunning everyone in the delivery room.

And they have remained inseparable ever since.

Five years on, and the girls' bond has only grown stronger.

They are remarkably close.

Speaking to People, Sarah explained, "Sometimes if my husband goes to the store, he’ll take one twin and I’ll keep the other. When that happens, they both get really upset and ask for each other. They’re definitely really close. They’re like two peas in a pod."

They share the most unique connection.

“If one twin is crying, the other will try to find a way to comfort her, like going to find a pacifier or rubbing the other’s back or offering a hug," Thistlwaite continued. “They always take care of each other."

The girls have always shared the same interests, too.

“They like the same foods, they both love swimming and being outside, and they love to play with the same toys," Thistlethwaite says. “We try to buy two of everything to minimize competition, but still, they usually find one to fight over – even if they’re exactly the same."

And they've already learned to use their likeliness to their advantage.

“If Jenna does something bad, I’ll ask her about it and she’ll say, ‘No, Jillian did it!’" Thistlethwaite says. “But they look so much alike that sometimes I really can’t tell which one of them is in trouble."

They're already the best of friends.

And they always have been! Sarah noted just how lucky her daughters are to have one another: “Twins have such a special bond and I can’t wait to watch them grow up and continue being best friends."

Twins are just the best, okay?

Even now, twenty-four years down the line, I still can't get over my luck. A sister and a best friend rolled into one? What can get better than that?!
