Where does it go!?

For some unexplained reason, a couple of days ago I started thinking about where my tongue is in my mouth. Just where it regularly resides when I am not talking. Suddenly, I couldn't recall! Where did it go? Against the top of my mouth? On the bottom? Behind my top, or maybe bottom teeth? Nothing seemed right. It resulted in me being fully conscious of where my tongue was in my mouth for two whole days. As if I didn't have enough things to think about already. Thankfully, I have forgotten to think about it now. The whole event reminded me of the time when I was 11, and I started to think about how often I unconsciously swallow saliva...
