I just followed my genetic heritage from Southern India through the Middle East and Caucasus into Europe. Apparently I'm Aryan as fuck. And I don't mean that in a racist way, but I have remnants of Middle Eastern and South Asian DNA, enough to cause Behçet's Disease to express itself in me. One site's algorithm lists 96% European (Mostly Eastern European, Scandinavian, Italian, and Iberian) 4% Caucasian (Iranian), the second lists ~99% European, <2% South Indian Peninsula, and the third lists 97.7% European, 2.3% Middle Eastern. My Ancient Heritage lists Yamnaya, Corded Ware, La Brana 1, Ötzi, Motala, and a few others.
As Behçet's Disease is called the Silk Road Disease and is very rare in people of European and Western Descent, this makes a lot of sense. My family were obviously early Indo-Iranians that traded or at least migrated along the Silk Road.
