fashion job

I was watching PGKNB earlier today wherein Doctors and staffs from St. Luke's Hospital were the ones who played on their special round. Anyways, I noticed that there were a contestant who wears a very fashionable medical id necklace. At first I thought it was some sort of a logo or something but when the camera slightly focuses on her face and neck then I realized it was a medical thing related! It was so nice and it's like being so proud to what you do in real life, aside from the College ring most of the career peeps wear.
