Each morning, we coalesce in a sleepy fog, winding our way up two stories of spiraling stairs. At the entrance to the anatomy lab, refrigerated air heaves the sweet, pungent tang of formalin into somnific faces. The first blow lands hard, without fail. Fluorescent lights sting bleary eyes. Acrid fumes burn their way up nasal passages, down tracheas, through bronchi, and deep into the minute alveolar sacs of each pulmonary lobe, radiating an analgesic chill in their wake.
