I'll believe in the combat applications of pressure points as they are (not disputing the existence of vulnerable spots, just magical asian points) when they start being used effectively and consistently in the myriad of combat sports and contests across the world, where they're not actually banned at all. And like, rather than look for a point under the armpit, protected by a person's ability to retract their arm, it seems far simpler to aim for the sternum or liver or ribs which are consistently targeted to great effect.
