Carotid nerve plexus....not the arteries. As teenagers we used to do this in addition to a couple of other really stupid things that'll cause a person to pass out. This is something I can say from first hand experience can make you pass out. Wasn't until the Internet got big we were able to know how it actually works. There was another we did which involved bear hugging around the chest. Slower than the the neck thing but also worked.let someone who is trained in any striking art tap it, with the idea of knocking you out...
See how it works out..
Blood choke,,,,how does it work
does it take both arteries or just one,,
What about the other 2 or 3 ?
anyway,,,in answer to the OP...
Did watch Dillman, in person.
Noticed that most if not all his taps,,,ended with one touching the neck...
the movements very quick and precise..
As to "light" or "heavy" probably around
5 lb or more of force, not much
Not a good idea to let anyone hit or strike the neck or throat area.... even in practice..
