I admit it. When it comes to all this new prosthetic technology, my “edge” is a little dull. Still, I keep hearing about it in the news. A recent article in my local newspaper called it “amazing technology”; a television anchorman referred to a recent advance as an “incredible accomplishment.” You might recall when a German scientist told the world that Oscar Pistorius prosthetic running legs “give him a clear edge over able-bodied runners.” Not too long after that, one of the largest automakers in the world debuted a television commercial featuring an amputee running using one of those same carbon-fiber blades. And a while back, someone sent me an e-mail about a gentleman who claims his computer-controlled knee saved his life by helping him descend 63 flights of stairs in his escape from the World Trade Center on September 11.
