HumBio area of study: Neuroendocrinology.
One day in the Core, my good friend was sitting next to me and, about fifteen minutes into class, whispered that she felt really nauseous. Before we knew it, she had thrown up (albeit quietly) in her own lap. Stunned, we implored her to go home and clean up/get better while we cleaned up the mess. Shockingly, barely a single Core student noticed that this had happened-- everyone was disbelieving when we told them that another student had thrown up and left class in the middle of lecture! From then on, she uses that story as an example of just how focused Humbio students are.
