(WXYZ) - A picture showing a marine weightlifter and a Detroit girl fighting a rare disease is capturing hearts all over the world.

David "The Beast" Douglas calls 12-year-old Lindsay Ratcliffe his "little sis."

Lindsay suffers from a genetic disorder called Progeria.

The photo shows David wearing a shirt that says "strong" across his shoulders and "stronger" with an arrow pointing to Lindsay as he holds her hand.

David says people call him strong, but everything about Lindsay is stronger.
