Congratulations topic creator you have turned this lurker into a poster I hope you feel bad.
on topic I'd say no since it'd be an insult to improving your self, also I'd either use EMP devices(if one happens to be lying around or just a comically over sized magnet ( I could make one if necessary) and laugh at all you disfigured bodies with metal sticking out of them, then I'd have lunch , then I'd destroy you all. also the issue of rusting and worn machinery is an issue it wouldn't just be old people replacing their hip joint.
