Yes, VR; and I believe I have two, not just one, guardian angels....
I do not wish to rude or offensive, but I have a deep problem with the concept of guardian angels. What do they guard? Our physical selves?
I spent most of a decade dealing with families that abuse and neglect their children. And these were American kids, infinitely lucky by world standards. It always struck me that angles who guarded healthy and capable adults should visit the ghetto occasional and guard unlucky children.
And you're probably wearing them to a frazzle.
Here I was peacefully catching up in this thread and I come across this.... Like the fish who finds a favorite food skwirming on a one stranded metal swingset, I have to check this out please.
Why... two?
I don't think Mr. Asimov will mind the diversion.
