that's whats up

So, as you may know by now, I have this incredible curiosity and admiration for prosthetics and the people who use them. The carbon fiber, blade style extensions (sported here by Aimee Mullins) are not anything new at this point. I had to post this pic regardless because I cant help but think they're amazing. According to Professor Dr. Brüggemann of the German Sport University in Cologne, "once the runners hit a certain stride, athletes with artificial limbs needed less additional energy than other athletes" giving them a controversial advantage over their competitors.
