Vale Tudo
The reason why this sport is extremely dangerous is because there are very limited rules. It is lethal in a sense that it follows the “anything goes” philosophy. This is a Brazilian martial art, but you might not have heard of it before. It is less popular relative to Capoeira and Jiu Jitsu. This is more like a life and death martial art that most people don’t dare trying. Usually, fights are held underground because the process is too brutal.
