The magician interviews Madge over at Interview:
BLAINE: …So I stayed in a box for 44 days in complete isolation. It was a self-imposed solitary confinement. But … I want you to close your eyes. Can you imagine what it actually feels like to be completely isolated, all by yourself with nobody to talk to?
MADONNA: For 44 days?
BLAINE: For a day. Have you ever done that?
MADONNA: No.
BLAINE: Okay, so think about it. What would it be like?
MADONNA: I'd really enjoy it at this point in my life.
BLAINE: Keep your eyes closed.
MADONNA: Okay, sorry. I think I would really enjoy it, stillness and quiet, because I feel like people are always talking to me, at me, asking things, questioning me, wanting information, work, music, loud noises, children—it's endless. So the idea of a whole day of silence sounds very seductive to me.
BLAINE: What do you think your brain would fill up with?
MADONNA: Ideas. [both laugh]
BLAINE: Ideas. You can do that while you hear noise.
