Like
 most 23-year-olds, Abby and Brittany Hensel love spending time with 
their friends, going on holiday, driving, playing sport such as 
volleyball and living life to the full.

 The
 identical, conjoined twins from Minnesota, in the United States, have 
graduated from Bethel University and are setting out on their career as 
primary school teachers with an emphasis on maths.
 Although they have two teaching licences, there is one practical difference when it comes to the finances.
 "Obviously right away we understand that we are going to get one salary because we're doing the job of one person," says Abby.
 "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."
 "One can 
be teaching and one can be monitoring and answering questions," says 
Brittany. "So in that sense we can do more than one person."
 Their friend Cari Jo Hohncke has always admired the sisters' teamwork.
 "They
 are two different girls, but yet they are able to work together to do 
the basic functions that I do every day that I take for granted," says 
Hohncke.
 The twins know each other so well that they often say 
the same things or finish each other's sentences, and are supportive and
 understanding of the other in all aspects of life.
 With two sets
 of lungs, two hearts, two stomachs, one liver, one large intestine and 
one reproductive system, they have learned from a young age to 
co-ordinate their body, with Abby controlling the right hand side and 
Brittany the left.

 There
 is a difference in height and at 1.57m Abby is taller than her sister 
Brittany who is 1.47m. As their two legs are different lengths, Brittany
 has to stand on tip toe, on her leg, to ensure they maintain their 
balance.
 They have had to learn to reach compromises on 
everything from what food they eat to their social life and even the 
clothes they wear.
 "We definitely have different styles," says 
Abby. "Brittany's a lot more like neutrals and pearls and stuff like 
that, and I would rather have it be more fun and bright and colourful."
 While
 Abby is seen as the "outspoken" sister and will always win the argument
 about what they are going to wear, Brittany says her twin is also much 
more of a "homebody," whereas she prefers going out.
 There are 
other differences, too. Brittany is scared of heights, whereas Abby is 
not. Abby is interested in maths and science, while Brittany prefers the
 arts.
 They also respond differently to coffee. After a few cups Brittany's heart rate increases, but Abby is not affected.
 And they have different body temperatures.
 "I
 can be a totally different temperature than Brittany would be," says 
Abby, "and a lot of times our hands are different temperatures, so I get
 super-hot way faster."

 Despite
 having a normal family and social life, studying and working like any 
other young women, they do face some additional problems.
 For 
example, they have to put up with speculation about their private life -
 something they prefer not to discuss. The twins deny a rumour that 
Brittany has become engaged, describing it as a "dumb joke".
 Travelling
 to a new country with friends on holiday is also not as straightforward
 for conjoined twins. They have two passports, but one ticket as they 
only take up one seat on the aeroplane. However, they also have to be on
 their guard and more aware of entering crowded or confined spaces 
because members of the public will often try to take unwelcomed 
photographs.
 {read_more} As a close friend of the twins, Erin 
Junkans says you always need to be alert because you never quite know 
how people are going to react or what they are going to say.
 "I 
want to make sure that they're safe and that they're not completely 
exposed, definitely just standing in the way of pictures, just always 
keeping an eye on what's going on and just how the girls are reacting to
 the crowds," says Junkans.
 "Sometimes if they get more 
overwhelmed then… we just need to get away from [the] area for a little 
bit, but they amaze me at their ability to just shake it off and keep 
seeing what we are there to see."
 Conjoined twins are very rare -
 it is thought one in every 200,000 births - and around 40-60% of these 
births are delivered stillborn. Female siblings tend to have a better 
survival rate than male siblings.
 Any operation to separate 
conjoined twins is a highly complex and dangerous process. It was a risk
 that Abby and Brittany's parents did not want to take for fear that one
 of the twins might not have survived the surgery or have the same 
quality of life they do now.
 With possibly fewer than 12 adult 
pairs of conjoined twins across the world today, Abby and Brittany 
Hensel are defying the odds. Their mother, Patty Hensel, says her hopes 
and aspirations for her daughters' future are just the same as anyone 
else's.
 "Like every mum would hope for, you want them to be 
successful and to be happy and healthy as they're being successful, and 
that's what I want," says Patty Hensel.
 As they embark on their 
working life together, the twins aim to take things day by day and do 
not tend to look forward to where they will be or what they will be 
doing in 10 years' time.
 With their position as teachers they 
have become role models for children academically, but also in their 
attitude to life, overcoming any challenges.
 "I don't think 
there's anything that they won't try or something that they couldn't be 
able to do if they really wanted to," says Paul Good, principal of the 
school where Abby and Brittany work.
 "To bring that to children, especially kids who might be struggling, that's very special, that's learnt through lived example."
