"That's good" is what that meant, right? How do you say "very?" Because I think it needs a "very."

I can totally see how that would work, and it makes sense from an engineering perspective. I don't know how your teleporting works exactly, but moving mass from one place to another takes energy. Human bodies are just really awesome machines, you know. Most machines are built to emulate people for that very reason.

.. heh. [He rubbed the back of his neck again, obviously his go-to nervous gesture] Which is engineer talk for saying "no wonder you eat a lot."
