I nearly got knocked out in a muay thai class one time. I didn't have my hands up to my face, so when I got head kicked I basically exploded. That shit was so violent, it sucked. I wasn't concussed and they kicked me pretty lightly. I knew what is was like to be a Nazi insofar that I was defeated because of the violence. It was a good thing because it taught me to take better care of my nutrition because I think it was a factor in running out of energy and getting hurt. I didn't get killed, so it was just a learning experience.
