Apologies if this is not an Ask Lemmy worthy question, but I couldn't guess an appropriate community to post it to and welcome suggestions to where to move such a question to.

Question is as in the title: how could Batman survive what really seems like a deadly stab by Miranda Tate (=Talia Al Ghul) at the end of the movie and still have the strength to go chase the bomb, the lucidity to set up the autopilot and the coordination to jump off of the bat(wing) to safety?

Wouldn't he have bled to death (and very quickly too, even if she was trained to miss internal organs)?

We're shown that she twists the blade too and he feels the pajn (so the armor didn't really protect him).

Of course, the standard joke answer is that he's the Batman (so he can take it when others can't).

The movie is fiction and not intended to be realistic, so there really is no need for an explanation, but at other times it explains things to us. For example, the autopilot explanation at the end of the movie or that, even if it is unrealistic to heal his spine and be able to withstand several botched falls from prison, at least we're told that he's nursed back to health by the doctor inmate.
