Is it true about gold rings and anemia?
I have been told a test,(although i guess not exacltly very accurate)you can quickly do yourself to test for possible anemia is to rub a gold ring down the skin on your face.
When this happens on certain people a black line appears, apparntly this is susposed to mean you have low haemaglobin or iron or something so it could be possible anemia.
Is there any truth in this?
