Abigail Loraine Hensel and Brittany Lee Hensel (born March 7, 1990) are American conjoined twins. They are dicephalic parapagus twins (having two heads joined to one torso), and are highly symmetric for conjoined twins, giving the appearance of having a single body without marked variation from typical proportions. Each has a heart, stomach, spine, pair of lungs, and spinal cord. Each twin controls one arm and one leg. When they were infants, learning to crawl, walk, and clap required cooperation. They can eat and write separately and simultaneously. Activities such as running, swimming, hair-brushing, playing piano or volleyball, riding a bicycle, or driving a car require coordination. The twins' lives have been covered in the popular media, including Life magazine and The Oprah Winfrey Show. They were interviewed on The Learning Channel in December 2006, discussing their daily lives and future plans. They starred in their own reality television series, Abby & Brittany, on TLC in 2012. Since 2013, the two have been teachers in Minnesota. Background The twins were born in Carver County, Minnesota, to Patty, a registered nurse, and Mike Hensel, a carpenter and landscaper. They have a younger brother and sister. They were raised in New Germany, Minnesota, attended Mayer Lutheran High School, in Mayer, and graduated from Bethel University, in St. Paul, in 2012. Physiology The twins have a single body with separate heads and necks, a chest that is wider than average, two arms, and two legs. At birth, they had a rudimentary arm between the bases of their necks attached to a shoulder blade at the back. It was removed, leaving the shoulder blade. Abby's head tilts laterally outward about 5 degrees to the right, while Brittany's tilts laterally at about 15 degrees to the left, causing her to appear shorter even when seated. Brittany's leg is nearly two inches shorter than Abby's and Brittany tends to stand and walk on tip-toe which has made her calf muscle significantly larger than Abby's. The continued growth of Abby's spine was surgically halted after Brittany prematurely stopped growing. At age 12, they underwent surgery at Gillette Children's Specialty Healthcare to correct scoliosis and to expand their chest cavity to prevent breathing trouble. Each twin manages one side of their conjoined body. The sense of touch of each is restricted to her body half; this shades off at the midsagittal plane, so that there is a small
