STank BrEAth!

Today at church my mind started wandering. I was thinking about my stank nasty breath and I just started thinking about all the different types of bad breath. I was supposed to be playing the piano, but I was playing songs I've played many times so I start not concentrating as hard as I should on the task at hand. Anyway, I was thinking about how bad breath has varying levels of stink and varying levels of distance it travels out of the mouth. I know this is random, but some people's bad breath travels far and wide with a certain thickness to it. Some people's breath travels short distances- still really bad, but you only get a wiff here and there. I don't know- what causes the difference in coverage? Any thoughts- I'm just curious because it made me chuckle a bit while I was supposed to be playing "Choose the Right".
