Ernest is an 18-year-old boy who has stopped aging and conducts meticulous daily examinations of his physical condition in a bathroom. He carries medical equipment to the sink and records his observations in a voice recorder. Ernest examines his skin, eyes, teeth and notes that his acuity, density, and number of cavities have not changed from the previous day's examination. He smiles as he examines the strength of his enamel and interior of his mouth.
