The Hensels were born in Carver County, Minnesota. Their parents are Patty, a registered nurse, and Mike Hensel, a carpenter and landscaper. The twins have a younger brother named Dakota, or Koty for short, a younger sister named Morgan, and a dog named Sadie.

Brittany’s head is about 15 degrees laterally outward, while Abby’s head tilts laterally outward about 5 degrees, causing Brittany to appear to be slightly shorter. They were raised in New Germany, Minnesota and attended Lutheran High School affiliated with the Missouri Synod in Mayer, Minnesota. At age 12, they underwent surgery at Gillette Children’s Specialty Healthcare to correct scoliosis and to expand their chest cavity to prevent future difficulties with breathing.

Each of the twins manages one side of their conjoined body and are quite effective in cooperatively using their limbs when both hands or both legs are required. By coordinating their efforts, they are able to walk, run and ride a bicycle normally — all tasks that they learned at a normal speed. Each writes with her hand. Together, they can type on a computer keyboard at a normal speed. The sense of touch of each is restricted to her body half; this shades off at the midsagittal plane such that there is a small amount of overlap at the midline.

Separation Upon their birth, their parents rejected the option to attempt surgical separation after hearing from doctors that it was not likely that both girls would survive the operation. As the girls grew and learned to walk and develop other skills, the parents confirmed their decision against separation, arguing that the quality of life for the surviving twin or twins living separately would be less than their quality of life as conjoined beings.

Adulthood. They both successfully passed their driver’s license exam, both the written and driving tests. They had to take the tests twice, once for each twin. Abby controls the pedals, radio, heat, defogger, and other devices located to the right of the driver’s seat, while Brittany controls the turn signal and lights; together, they control the steering wheel. They also want to visit the UK, so they can both have a chance to use their opposite controls. They both graduated from high school in 2008.

They began college at Bethel University in St. Paul, Minnesota, USA. In conversation, they are clearly distinct persons, with distinct likes and dislikes. The twins’ preferences in food, clothing color, etc. differ. Some of their clothes are altered by their seamstress so that they have two separate necklines in order to emphasize their individuality. They will usually have separate meals, but sometimes will share a single meal for the sake of convenience (e.g., each takes a bite of the same hamburger).

Abigail is better at mathematicsgrammatical person is to use the first person singular out of habit when they agree, but when their responses do differ, they use their names in the third person singular. and Brittany is better at writing. For tasks such as responding to e-mail, they type and respond as one, anticipating each other’s feelings with little verbal communication between them. In such cases as the latter, their choice of There is some concern about their ability to have continued good health because only four known sets of conjoined twins who share an undivided torso and two legs have ever survived into adulthood, and most have congenital heart defects or other organ anomalies. None have shown up in the Hensels’ case.

They have so far had no desire to make themselves available for any medical studies. They intend to make a rather limited number of media appearances in the future, primarily just to appease the world’s curiosity and to reduce the number of people who might otherwise be taken aback by their unusual body configuration. They intensely dislike being stared at or photographed by strangers while going about their private lives.

They expect to date, get married, and have children. They hope that by providing some information about themselves they will be able to lead otherwise fairly typical social lives as together they continue to make new friends.

Media appearances. In April 2006, they appeared in Joined for Life, a documentary produced by Advanced Medical, distributed on the Discovery Health Channel. They also appeared on The Oprah Winfrey ShowLife under the caption «One Body, Two Souls», and their daily lifestyle was depicted in the corresponding article titled The Hensels’ Summer. Life followed up with another story in September 1998. In 2003, an updated story of them at age 11 (filmed in 2001) was published in Time and again in Life. They appeared in a follow-up documentary on The Learning Channel on December 17, 2006 filmed around the time of their 16th birthday, in which they discuss dealing with pubertydriver’s licenses.
