Over at JillStanek.com, LauraLoo has posted a video that is so astonishing it’s hard to believe that it’s true. It’s all about Olympic gold-medallist gynmast Dominique Moceanu and her discovery of a sister she never knew she had, because she was given up for adoption at birth.

But it’s not the mere fact that she had a sister who was adopted as a baby that is so amazing. What’s so unbelievable is that her sister was born with no legs, but despite her disability, has gone on to become a competitive gymnast. In fact, long before Dominique’s sister ever knew that the two were related, she had idolized Dominique as her favorite gymnast.

It’s a pretty incredible, and very heartwarming story. Check it out.
