Yeah, what Faldage says.

I don't think of words as being physically stored in my computer or my brain. What are the dimensions of a word, what's its mass? Does my computer/brain get heavier with each new word I store? Is "it" smaller, lighter than "Rumpelstiltskin"? How tiny must the tweezers be to pluck it out? What's its chemical composition, its reactivity? Solid, liquid, or gas? What color? Nope, I can't buy it, either.
