South African runner Oscar Pistorius is competing in the Olympics this year. What are your opinions on this matter? I think it is a wonderful example of courage and strength. That can't be denied. But if I am going to be honest here, there is a part of me that really wonders if it is fair or not. Obviously he is at a disadvantage being a double amputee. But do the fibre blades give one an advantage? In the future, with all the science and advanced technology, could there be "super" humans capable of physically more than even an Olympic athlete?
