🤺 Did you know? Shoulder, knee, hip — these body parts are frequently used in business English too: "shoulder the responsibility," "knee-jerk reaction," and "hip to the problem" are all common idioms. Outpatient vs. inpatient — an outpatient receives treatment without staying overnight; an inpatient is admitted and stays in the hospital. This distinction matters in health insurance and medical billing. "On the mend" is a common English expression meaning recovering from illness: "She was out last week but she's on the mend now." Very natural in workplace conversations.
