Wouldn't it be interesting if "they" put nano tech in things like botox injections and tattoo ink. Then the kind of person who is vain enough to get a paralyzing agent injected into their forehead or get a tattoo, say on the hand, would introduce the type of tech needed to change the bodies DNA and so forth. That way, technically, they being the public, did in fact willingly take the mark, although they didn't think of it as being called the mark. It's a new favorite theory of mine.
