following human logic. you can ask what change could they bring in.
for example, years back i read , have also heard people talk about, the mark that is spoken about in rev.
see, id cards, can be lost or stolen, a chip used in dogs, could be use for humans. hence looking at how this mark or chip is connected to rev, and how human logic could force, governments to use something like this. and if they started something like this, then it would not belong before all walks of life, would be forced to have there mark etc.
