In the above video, they got some doctor to analyze the injuries that John McClane would have suffered in the first Die Hard movie. While I believe the exercise was interesting, the doctor definitely took some liberties with his diagnosis. A concussion by simply breaking through some dry wall? The dry wall that I’ve seen wouldn’t really even give most people a bump on the head. The doctor seems to take the worst-case outcomes in all the scenes. Anyways, it’s still neat to hear all those fancy medical terms.
