Having a sister usually means a friend for life.
For Abby and Brittany Hensel - it means a lot more.
The 22-year-olds from Minnesota are conjoined twins. Abby controls the right side of their body, and Brittany controls the left side. They can dance, ride a bicycle, and even drive a car.
They work hard everyday to live "a normal life … whatever that is."
Here's what they said:
"People have been curious about us since we were born, for obvious reasons. But our parents never let us use that as an excuse. We were raised to believe we could do anything we wanted to do. The most amazing thing about us is we are like everyone else."
A new reality series will follow their lives as they graduate from Minnesota's Bethel College and head to Europe where they will search for a teaching job.
Here's what Abby said:
"When it comes to decisions, there are compromises we have to make. We take turns. We want to work it so each of us is happy and we find a happy medium."
Only once out of every 200,000 live births are conjoined twins delivered. Only about 35 percent survive more than one day. Medically speaking, what the twins have accomplished so far has been nothing short of a miracle.
Here's what a doctor said:
"All conjoined twinning is really uncommon. But the chance of a mother delivering a set of conjoined twins and their surviving is one in a million."
Those odds don't scare or defy Abby and Brittany.
It just gives them even more motivation to succeed at this crazy thing we all know as life.
