Re: Odo knew Neck pinch?
I think I heard that pinching nerve clusters where the neck meets the shoulder actually can briefly render a person unconscious. Vulcans just have the physical strength to administer it like it's nothing. Data used it on several occasions. And Picard used it once (on a character played by Tim Russ ironically), although with extra effort than most Vulcans.
And Seven of Nine used it on Tuvok.
