Art style: 3D animated simulation.
A middle-aged man with salt-and-pepper hair and a short beard. He wears a white lab coat over a blue shirt and has a stethoscope draped around his neck. He carries a medical clipboard and has a serious yet professional expression. He is seen in a clinical hospital setting with medical monitors and equipment.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D animated simulation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D animated simulation". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "3D animated simulation" idiom, not in any other medium.
