I've wanted to be a doctor since I was a kid. I remember going to the Field Museum in Chicago, standing in a giant replica of heart and listen to a recording of its beating. It felt like being let in on a secret, a secret that I could use to stop heart attacks one day. Like a real super hero. But along the way felt less sure. I worried about the ways that doctors change during their training, from the cut-throat competition in college to the hierarchical nature of training, which distances us from our patients and each other. - Dr. Poorman
