Prosthetic Arms a Complex Test for Amputees - NYTimes.com: So there he was one recent afternoon, kayaking down the sun-dappled San Marcos River, using the wrong prosthesis because he had broken his kayaking limb while surfing. Normally he is at the front of the pack, but today his arm kept slipping off and he seemed in pain as he struggled just to keep up.
Yet he said nothing that could be heard as a complaint. And at the end of the six-hour trip, he went over the 14-foot Graduation Falls, the first time he had done so in a boat. After dropping vertically into the frothing water, his kayak momentarily disappeared beneath the surface before popping out like a cork.
Eyes smiling below the brim of his helmet, Corporal Gallegos paddled to shore, hefted his boat onto his good shoulder and started the trudge upstream.
He did not ask for help.
