Corey writes, “I got this tattoo as an homage to the pain of my graduate work.  It’s a model of fulvic acid which is a representation of natural organic matter in the soil. I work with this molecule for my grad work and I figured I might as well get it etched into my skin so I can look at it and say, ‘Well, at least it hurt less than grad school at Cornell.'”
