have no idea, never heard of that. i'm an idiot when it comes to my health care. i've only ever been to the doctor when i have a problem. have been in and out of health insurance so to me going to the doctor is an extremely expensive thing to avoid. especially when doctors are dismissive about whatever issue i come with. i've never been for preventative care, don't even know what i would say when they ask what i'm there for.
I am a physician in the US and have done this before (prior to medical school), so I had always thought it was (still) possible.
