Couldn’t it be on the subject? Not for pregnant women, right?
For the diversity, some of the history:

The plate armor of the Mongols, inherited after them by many peoples, was called "huяг", in Russian pronunciation "huyak".
The word entered the Russian language, so there were often reports of Siberian Cossacks about the tribes going out to battle, horseback, armed and hooked. Or reports of a meeting with the "Ohuyachan Kalmyk" unit.
