Abby and Brittany Hensel are conjoined twins determined to live the normal, active life of outgoing 20-somethings anywhere. They have been to university, they travel, they have jobs. But how easy is it for two people to inhabit one body? 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. "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." 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.The identical, conjoined twins magazine 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. "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.
