Smart things about Urine

This is from last month's Wired magazine, but it's something that I can't help but think of now when I go to the restroom.  It's 3 smart things about urine.  Yes, it is something odd for me to blog about, but the article keeps popping into my head (especially the delayed gratification thing), so I thought I would share it.  I apologize it is an awkward thing to blog about, but I enjoyed it.
