Woman with 1 arm becomes competitive rock climber - High school students design prosthetic leg for dog

Sianagh Gallagher of York was born without a left arm, shoulder blade or collarbone -- but that didn't stop her from taking up rock-climbing nine years ago, and becoming the captain of her country's paraclimbing team. "Growing up with my disability never really held me back from doing anything. If anything, I was more determined to get things done and prove myself to people," Gallagher, 19, told Barcroft Media. Gallagher -- Europe's lone paraclimber -- struggled to learn how to tie her shoes and peel an egg, but was at ease working her way to the top of a rock wall. "It was the first time I'd been really good at a sport," she said.
