I have a health insurance card. That in itself isn’t particularly surprising, as where I live, health insurance is obligatory. My card is special though because I made it so – I had my academic titles added on it because I could. Where I live, academic titles are a decorative property – it won’t earn you a living, but it will earn you a better approach from people. I’d almost venture to say that my PhD secures me a humane treatment, but I don’t want to push my luck too far.
Since you present your insurance card to staff before you are granted any treatment at all, the staff that will attend to you will know that you’re a fellow doctor. It’s seriously working wonders. Some of the doctors and nurses I dealt with were not only polite, they were positively friendly. I know this to be not the default behaviour. As all of them took vivid interest in my titles and inquired how to enter them in the correct order in my medical files, I’m sure that it was a smart move to adorn my insurance card with the little extras that make people treat me nicer.
