Hi all! I recently came across an article that suggested the Norse Vikings were the first to disseminate MS throughout the (known) world. There are obvious connections between Vitamin D and northern climates and the frequency of MS but how many of us can say with some degree of certainty that we might be descended from Vikings? I'm a medieval historian so I'm always thrilled by these historic connections! I'm definitely a Celt, from both sides of the family, though I've always adamantly denied that the Vikings could have defiled my ancestors' pure Celtic blood. I'd say the ghosts of Vikings passed are laughing at me right about now. Thoughts?
