I've also got "bad air" coming from my words and my thoughts. I spent a lot of useless time today worrying about something that turned out to be OK. And, I've been miscommunicating some.
I'd like the bad air in my head to blow on out, leaving clean, pure thoughts and simple energy. I'd like some fresh air to blow through my mouth, and make my words clear and easy to understand.
I'd like to be able to breathe deeply and not worry about what I'm taking in. I'd like to exhale all the yucky air.
