I currently train Brazilian Jiu-Jitsu @ Gracie Barra Calgary, Canada. I'm actually a black belt who's fought 1000 ninjas the black wore out into a white. Kidding. Maybe. [edit: I'm a blue belt now,I have less excuses to make]
What’s interesting is that both the attacker and the defender need to be responsible. I know from experience, there are chokes that come on quick and I’ll know when to tap out. It’s the slow chokes that creep up that are risky. I’ve tapped in the past but stubbornly fighting through it will certainly attribute to me .This video is a great way to learn about how the science and dangers behind the choke. Of course these two fellas aren’t Bill Nye or Beakman themselves. But can you IMAGINE if they were? Anyways bottom line: safety is paramount.
