You know, I was watching one of many Chinese dramas that you can dig up online last night (my wife is Chinese, she likes them because the sound tracks are in Mandarin, lol). In this particular show a major character tells the main character "This guy is a level 8 killer, you can't beat him, you're only level 7!" and then the fight is on and the two of them fight this guy, one dies, the other one wins. The main observation is there's NOTHING like your "flesh is weak" going on here. People are hurled clean through stone walls, flung 40' into the air, have giant 500lb stone crocks smashed over their heads, etc. Sure, they suffer, in the end one character dies, but there's no sense WHATSOEVER of any of them being anything close to ordinary people in terms of sheer physical toughness.
