Some voices outlast the people who spoke them. In his Crossroads blog, “The Voice that Lingers,” (June 19, 2026 Intima) Kenneth Iserson, a professor emeritus of emergency medicine, tells it as a physician: the dead mentor keeps speaking in a student's stethoscope, in a resident's patience at two in the morning, even in the margin of a machine's report that has learned to wait before it concludes. The voice refuses to be deleted — not because anyone saved it, but because it had gone in too deep, beneath the skin, beneath the name, where not even death goes looking.
