What would you do with yourself or to others if the following was true; you cannot be killed. You are NOT super anything but somehow death used your page to roll a joint and doesn't know you exist.
You can be overpowered, you can be wounded (and you will feel every bit of pain), you can be dismembered (and given time everything will reattach to complete functionalitiy), you can be burned (in few days you will recover), but you cannot be killed.
