I've learned too much...

I just arrived back in my apartment in Detroit after a weekend at my parent's home.  One of the first things I had to do after my drive back was use the toilet.  And I noticed that the water level on my toilet had significantly decreased...then I got to thinking...

...the humidity in my apartment must be low, meaning that the partial pressure of water is not being met for the temperature in my apartment, and so any available water is being vaporized into the apartment atmosphere, which includes my toilet water...and my roommate's toilet water...which means that I'm breathing in toilet water...lots and lots of toilet water...because we don't have any other sources of water sitting out anywhere else...

And that is when I realized that I've learned too much...
