After Neo learned kung fu, Neo and Morpheus connected to Matrix for a sparring program similar to the programmed reality of the Matrix. After the training, there was a conversation between them;
- Morpheus: How did I beat you?
- Neo: You... you're too fast.
- Morpheus: Do you believe that my being stronger or faster has anything to do with my muscles in this place? Do you think that's air you're breathing now?
Are they really breathing air when they in the Matrix? Or it was also just an another control system? Is there any information about that?
