I was looking at this today:
https://en.wikipedia.org/wiki/Folk_wrestling
https://en.wikipedia.org/wiki/Boli_Khela
Thought of opening lathi-khela thread.
Anyhoo, point is there is one form or type of wrestling or another in virtually every part of the world. Whether sumo, Hawaiian, monipuri, oil, mud, lutte, Mongolian...etc it is really an interesting topic to look in..
