One weird thing about me is that I was never into highlighters in med school. Everyone else was. One day some drug company gave out these pens that had highlighters at the other end, and many of the students were almost salivating.
One day when I was studying with friends during third year, I noticed that the student next to me was highlighting stuff from the peds textbook. I glanced over at the page he was reading and I saw that he had highlighted every single line on the entire page with a single exception. I looked over and read out loud the single sentence that he had not highlighted:
"H. influenzae type b cellulitis is now very rarely seen."
