I went to a medical clinic for an electrocardiogram. While the technician was lining up her machine, I told her I have dextrocardia.

"What's that?" she asked.

"It means my heart is on the right side of my chest rather than on the left," I answered. "You should set up your machine to accommodate that."

As she attached the wires, she asked casually, "Tell me, have you had that for long?"
