Breathe through the skin, its called cellular expiration. Isn't there an expression that says, hang on by your skin? In fact that reminds me of a related idiom below. And it has to do with honesty (though not so much skin anymore).
Let's say you had a conversation with someone, in which you inadvertently told the truth. And he turned out to have recorded it and is now using it against you. Here's where you have to do research into how to get out of legal jam like that, you have to be creative. Personally I would just flat-out deny that that was my voice and that that was me (does not always work though), or just say that I was so intimidated by the other person's demeanor that my brain temporarily got jumbled and I started to speak nonsense for a little while. You know, use your imagination. Make it believable; convince the judge.
