What is "real"?
How do you define "real"?
If you're talking about what you can feel ... what you can smell, what you can
taste and see ... then "real" is simply electrical signals interpreted by your brain.

Data is any sort of raw fact. Information is data in a usable form, usually
processed in some way. It’s data plus interpretation.

What a piece of work is a man! how noble in reason!
how infinite in faculty! in form and moving how express
and admirable! in action how like an angle!
in apprehension how like a god!
Will Shakespeare (Act II, scene 2, of Hamlet)
the beauty of the world! the paragon of animals!
