The occurrence of twins is highly rare. Unique in terms of both their mental and physical connection; when we examine some fascinating facts, the topic takes on a whole new level of wonder. In case you weren’t aware, identical twins share 99.9 percent of their genetic material.

Sometimes, the twins are not even born on the same day; they were eight days apart. Because of their unique link, twins may share thoughts, emotions, and behaviors.

Wow, that’s hard to believe. Some extremely rare cases involve twins born connected at the body. Because of the risk of severe complications from organ fusion, the lives of the twins are at stake in these exceedingly unusual cases.

Bella and Abby have a deep friendship despite having forgotten their shared history as twins. They had to stay in the hospital for an additional six months after birth because their organs had fused.

If you’re into hard numbers, consider that one such occurrence can happen for every 60,000 births. They had a tough time getting started because they were chained to their chest and stomach, and doing so put their lives in jeopardy.

Surgeons had to take a chance in response to an urgent situation. Perhaps the parents gave their consent to the operation because they saw it as their last chance at life. Their experience and resolve ensured the success of the procedure despite the seeming double whammy.

The May 12, 2006 operation lasted for 12 hours and was performed by 17 medical professionals. Through all of their anxiety, the parents never stopped praying for their two little angels. The treatment was effective, and the family was able to return home in a little over a month.

After a number of years, the girls are in excellent health and are quite physically active. Gymnastics help Abby and Bella channel all that excess energy. It seems like they are always bickering, but it doesn’t stop them from enjoying playing together.

When the girls found out they could communicate with each other mentally, they were both astonished.

We are so happy for Abby and Isabelle that they have finally learned to appreciate everything good in their lives. Each of their stories is summed up by the words “One in a million” on their bracelets.watch below
