    EVERYTHING ABOUT: Conjoined Twins Abby And Brittany

    Conjoined twins, Abby and Brittany are a global fascination...so let's learn more about them!

    Meet Abigail and Brittany Hensel (If you haven't already).

    These girls are one of the rarest set of dicephalus twins in the world!

    Abby and Brittany came to be when a fertilized egg failed to separate inside the womb.

    You may have seen them before on Oprah, Life Magazine, or the documentary about them on TLC.

    The girls have to cordinate everything together and they don't always have the urge to eat or sleep at the same time either.

    Abby and Brittany have always been treated as two separate identities. They even buy 2 movie tickets when they go to the theater.

    Since the girls are two separate people, one twin can get sick while the other stays healthy.

    Now that the twis are full grown women, some questions have arose: What happens if one twin falls in love? Will they ever have children or wed?

    Did you know: female conjoined twins have a much higher rate of live birth and survival than male twins. Approximately 70 percent of all conjoined twins are girls.
