It's been 12 years since conjoined twins Abby and Brittany Hensel were given their very own hit television series, and since then, they've remained a social media staple.
By the sounds of things, however, some followers of the on-screen duo still have questions about their day to day, only a handful of which they've ever publicly addressed.
For those unfamiliar with the sisters, Abby and Brittany were born in 1990, going on to appear in Time magazine as youngsters, and they were featured as guests on The Oprah Winfrey Show.

Mass intrigue into their lives prompted TV execs to give the pair their own titular TLC series which ran for several years until 2012, and centred primarily on their time at university.
After Abby & Brittany came to an end, however, the sisters were hired as primary school teachers, with one even going on to tie the knot.
Abby married long-term boyfriend Josh Bowling in 2021, and since then - after flying under the radar for several years - she and Brittany have been inundated with questions surrounding the dynamic of their relationship.
"Having only the one guy makes it more confusing. What if they fight? What if one h/w set wants to divorce and the other doesn't?", one person questioned recently.

"One of the twins will be the legal spouse as far as the state is concerned. So it is theoretically possible that the other twin could someday decide to marry a different person", a Redditor suggested.
"But given the way they have had to harmonise their entire lives, I imagine they would find it easier to stick to being married to just one person."
The pair also revealed how they go about their daily lives.
The twins' job and education
Despite their fame, Abby and Brittany went on to obtain separate degrees from Bethel University and are elementary school teachers in their local town - with one salary between them.

Abby told the BBC: "Obviously right away we understand that we are going to get one salary because we're doing the job of one person.
"As maybe experience comes in we'd like to negotiate a little bit, considering we have two degrees and because we are able to give two different perspectives or teach in two different ways."
Brittany added: “One can be teaching and one can be monitoring and answering questions. So in that sense we can do more than one person."
How does their body work?
As dicephalus conjoined twins, the women have separate hearts and heads but share essentially everything else.

Abby controls the right arm and leg of the body, while Brittany controls the left, but it doesn’t mean they have to do everything together.
How do they eat their meals?
In fact, when it comes to eating, the pair will sometimes have separate meals, and they actually have two digestive systems and two separate stomachs, but share the same bladder and excretion system, which means eating one meal between them more convenient.
Can the twins drive a car?
To answer questions about their ability to drive, they explained that they passed their test on their 16th birthday as Brittany said: "Abby takes over the pedals and the shifter, we both steer, and I take over the blinker and the lights."

Their mother, Patty, added: "I don't know what would happen if they got pulled over for speeding.
"Would they each get a ticket or just Abby because it's her foot on the accelerator?"
Can they have kids?
More personal questions also slipped through as people wondered whether they could have children.
"That is probably something that could work because those organs do work for them," Patty explained in Joined For Life.
"Yeah, we're going to be moms," Brittany agreed.
She added: "The whole world doesn't need to know who we are seeing, what we are doing and when we are going to do it. But believe me, we are totally different people."
