There is a genetic disease that some may have that come from Caucasian peoples. It's when too much iron accumulates in the blood it can cause organ problems. It's called hemochromatosis and you can get checked for it with a test. The test can check for either a genetic marker (cheaper) that shows that your bloodline may have it or a more expensive test that shows if you do have it.

The cure is easy. Donate blood for a few months. It's real.
