Of the many experiences in MMA, the one I'd least like to experience is being choked out. That makes me different from Dewey Hammond from Hard for the Yard. In this video, he is choked out by Frank Shamrock, and it takes about .0005 seconds:
This gives me a little perspective on why a fighter might not be able to hold on for just a few more seconds when in a choke. It also gives me perspective on why I will run the other way if Frank Shamrock is walking in my direction.
