They SAID that they had worked out all the kinks with cyber-transplants. That replacing major bodily processes with cybernetics didn't have qualms or ramifications any longer. And they were mostly right. But they forgot to consider the sheer will of the human spirit, of what tends to linger past the expiration date. Only after getting some rather heavy cybernetic work done at a discount doctor do you personally recognize the potential...faults...with second-hand products.
