I assume you're referring to the casually dressed young medical students, there, Billy ... and not the biomed techs!

Dress them up? Dress them down more like! smile

You can usually make them out easily enough, though. They are the ones with semi-earnest expressions fixed on their faces, often found tottering about with folders clutched firmly to their er, breasts and stethoscopes dangling around their necks. And usually oblivious to what's going on around them, as they march (OK, sometimes they waddle) off to the canteen with some sort of "mobile device" pressed against their ear.

If you don't inspect ... don't expect.
