Survival
The sad truth is that conjoined twins do not thrive often. Even with the help of medical professionals, the survival rate for people born like this is low. The doctors claimed that the girls were likely going to suffer the same fate as most conjoined twins. A quick look at the statistics will let you know just how miraculous it was that they were even born. Just one in 189,000 twins are born conjoined! On top of that, only 11% of that figure are dicephalic prapagus twins. As you can see, the Hensel twins were already very special from the get-go.
Teamwork
The birth and lives of Abby and Brittany amazed a lot of people from all over the world. However, we daresay that no one was more amazed than their doctors! They check up on them regularly and could not get enough of them. They were born with two brains, two heads, two hearts, two stomachs, three lungs, and one reproductive system. Yes, everything from the waist up comes in pairs, while everything is singular from the waist down. What makes it impressive is that the twins get to control their side of the body as well! Of course, they have to work together for certain activities.
