They’re Very Active
Since the twins share the majority of their bodies, they’ve had to learn to work together to make it move. Thankfully they’ve had a lot of practice. The twins display an astonishing sense of coordination, each using one arm to perform tasks, including playing the piano, bowling, swimming, and other sports.
Abby, the right twin can’t feel anything on the left side of the body while Brittany, the left twin, can’t feel anything on her right side. Abby’s in charge of operating the right arm and leg while Brittany takes charge of the left arm and leg. Together they accomplish whatever they set their minds to.
