Like many of the students, Dr. I was baffled by how to assess my heart and lung function without breaching the fortress of my bra. Most students, while listening through the stethoscope to my back, simply worked around the bra. But Dr. I informed me he needed to unsnap it (no, he didn't use the one-handed technique). Then he stood in front of me, looked at my gown like a colonel contemplating an incursion, and struck. He peeled off the top of the gown, dropping it into my lap, slipped the bra off my shoulder, and left me hanging while he protractedly listened to my heart. (Dear Male Readers: Doctors don't strip their female patients.)
