An actor in my high school's production of "Fiddler On The Roof" injured his leg and was hobbling around on stage during dress rehearsal. Before dismissing everyone, the director told him, "Pump that leg full of vitamins!"
The director wasn't a doctor, and I don't know if the student followed his decree. I guess, however, when people look to you as an authority figure, you have to have commanding advice ready to dispense.
I wonder, though. If an actor started developing dysphonia and was barely able to speak or sing, would the director have said, "Pump that throat full of vitamins!?"
