Multiple sclerosis

Multiple sclerosis is genetic. It's Yamnaya, specifically.

As an autoimmune disorder, I'd figured everyone knew that already. Immune disorders exist because their carriers needed to fight off anthraces and smallpoces; same as the Sickle Cell exists against malariae.

I suppose it's that this particular disease hit the nervous-system, was the sticking point here. Ashkenazim get it too.

Well: now we learn, in the Polania and in the Ukraine, we weren't just taxfarmers, pace TOO. Fiddler on the Roof was right all along: many of us farmed... crops; and - for our purposes here - we kept flocks by night. Even the Christians have sung of this, about us.

I must ask after whether something like MS existed among nonYamnaya herders in the Old World. Like along the Zagros; like in Africa. (China, perhaps, had the Tocharoi who were Yamnaya.)
