organs (heart, liver, skin). This blood disorder afflicts people of European origin - most specifically Northern European origins. If left untreated, the excess iron will damage organs and lead to death.
A common phrase for this disorder is "Celtic Curse" because the majority of the people suffering (see dna chart here!) from it are of Celtic origins. But the disorder goes much further then just Ireland and Great Britain. The Celtic Curse is also common among the people from the countries bordering the oceans and seas by the British Isles. This finding has led some researchers to believe the mutation disorder originated within the Viking communities of Scandinavia. But as more and more research is done, the true origins may be discovered further to the southeast.
Would this excess iron also give these cultures an edge when it came to interacting with the Earth's geomagnetic fields of energy? Making them better dowsers?
