Have you ever had something small (like a gnat) stuck up your nose? It happens to me sometimes when I go for a run. Then you inhale sharply and it goes all the way down your throat. You can feel the motion as it goes down your nose because that particular path is not usually used in that direction.
When this happens, I feel like "Otolaryngology Man"... based on one of those pictures in the doctor’s office. I'm not sure what my special powers are, but I'm sure I have some.
This also explains, genetically speaking, why kids eat booger. It has nutritional value and, as such, I'm sure it played a role in our ancestors' survival over the years.
Ok, so maybe I shared a little too much on this one.
