Deep breath, only heard at the back of the throat

So, even the most cynical side of me must admit that the yogic breathing does kind of rock.  I mean really, it's just breathing.  Although as a massage therapist I am constantly telling my clients that they need to stop in their day and breathe.  I even recently read an article about a study that found out what it means physiologically when we sigh.  It apparently resets our entire breathing pattern, expands the ribs a bit, and also sends some messages to our brain...can't quite remember what those messages were. ...sigh...   Nope, still don't remember.  Anyways, the yogic breathing.  It's great.  It's kind of like a long, concentrated series of sighs.  And then the cynical bitch pops up when I get off work and says to just sit on the couch, you worked hard, yoga isn't really gonna make a difference in your day, blah, blah, blah.  Her voice gets quieter every day.  It's great.
