Here's an interesting find: Researchers have come up with an idea for artificial blood. Theoretically, if people were to replace their blood with nanoblood their bloodstreams would be free from viruses, bacteria and cancer, and they would be free from vascular diseases. So here's the question: As a species becomes more advanced, should it replace parts of its body with better-designed parts? Is this a sign of advancement -- the ability to reengineer and improve on nature?
