Do they age?
I'm not sure if this topic is mentioned in either of the movies, or the novel. But, how do these robot women age? Surely, most of these women, if not all, have friends or family of some sort. And, if they would perhaps visit them, it would be quite weird to see them looking exactly the same all the time, even 20 years or more later. Aging creams don't work forever! I love this movie and its premise, quite terrifying. But, the plot does seem to have some holes and I have so many questions. So, what do any of you think on this?
Another thing, would the men have to shut down the robots after a certain time? Because, you can't have some immortal wife walking around without someone noticing. I am probably stretching the story a little bit more than it was meant to be, but, idk!
