Jujitsu Rules in Fighting

There are certain ipalm throws that have happened on concrete like you're not getting up for sure. But there's also ipalm thrown that Wouldn't knock you out wouldn't disable you from continuing to fight but those are the rules. In MMA and in jujitsu there's a rule that says no small joint manipulation Yeah, all that means is I'm not allowed to grab one of your fingers and bend it and break it so It's not a game changer, but it prevents injuries So rules like that usually makes sense now look there's gonna be someone that says yeah If I broke your finger you might freak out it's true true life or death battle though Not happening.
