sorry, I wasn't clear.
I didn't mean to say that you should expect to be done if you get hurt, just that it would be unwise to expect being able to keep going as a matter of course.
I would fully expect myself to keep fighting until the lights go out, but I've been caught by enough punches boxing to know the lights can go out earlier than one expects. So, for planning purposes it's best to assume that if you get shot you'll be down - not that you should quit, but that you could very well be unconscious, in shock, or dead.
There are far too many variables resulting for getting shot for it to be worth much effort deciding what you'll do after it happens.
