everyone that trains stand up has had it. that one shot u didnt see coming that rocked your world. everyones a bit different. what hit you and wat did u experience? ive never been knocked out but this was the closest ive come. it was actually from my best friend in sparring we non verbally decided to crank it up a bit and bang i got a hook in neck/chin and the ground turned to slippery ice my vision turned into a fish eye lens with a black ring around it, sounded like a bell went off in my head and it took bout 5 minutes to truly recover. how bout u guys?
