When you get knocked out, time stops. You don’t think, you don’t dream. It’s like that period of time has been permanently erased from your hard drive. One moment you’re staring at your opponent, the next you can’t understand why a doctor is pointing a pen light into your eyes. The first time it ever happened to me, when I was competing in Chinese kickboxing at the Shaolin Temple, I felt as if I’d inadvertently stepped into a time machine and been transported 30 seconds into the future. My opponent had his hands in the air while for some reason I was lying on my back. It was a trip.
