think about this is a gaping hole in our body okay we have some other gaping holes in our body but those tend to be sphincter based holes yes I realize there probably some Chuckles as soon as you say sphincter like yes the anal sphincter okay we're anatomists we're biologists we can talk about that stay shut stuff is generally not going up there and if it is not very often okay your nasal passages yeah those are holes but you know there's a lot of stuff there there's mucus to catch stuff there's a CRI form plate there's a bone there's a bunch of things that act as barriers between the nasal cavities and the Brain which sits right behind it the olfactory bulb and yes we have eyes and then you know we have the outside of the eyes and there's a you know a susceptibility there but we have our blink reflex there's a also an ocular microbiome there's a bunch of things there but think about the just this gaping hole in the front of our face that we use to eat and speak and breathe okay it's a huge hole and as a consequence it's filled with bacteria from our outside environment all day long all day long
