Along the lines of blown out knees in gymnastics is the incredibly inspiring story of Shun Fujimoto, who injured himself during a gymnastics routine in the Olympics, and then kept competing.[1] Per the Wikipedia article on the guy, "One doctor stated: 'How he managed to do somersaults and twists and land without collapsing in screams is beyond my comprehension.'"[2]

Watching that video and reading his story quickly put an end to my complaints of "but I need a nice ergonomic keyboard to be able to work at all!"
