During middle school, I was fascinated with the natural world. At home, I enjoyed playing outside and finding bugs and butterflies. When my parents called me in for dinner, they often had to coax me out of a tree. In school, I was equally curious. I remember the excitement I felt in my sixth-grade biology class when my teacher dissected a cow’s lung. I patiently waited in line to put my entire right arm into the esophagus.
