@princ3,
Here's an explanation, but it's probably not of the sort you're looking for.
If any of that stuff exists -
highly, highly doubtful - then it is, by definition, expensive and difficult to create, manage, maintain and hide. And so if it does exist -
and I'm sure it does not - but if stuff like this is ever invented, your sister will never be a candidate for such a treatment unless she becomes President of the United States or an international assassin.
