I'm watching a TV show on Kung Fu and Dim Mak. One of the kung fu Dim Mak techniques is apparently a carotid artery attack. That's the same position as a rear naked choke, except the pressure is applied to the arteries instead of the trachea. Every Brazilian Jiu Jutsu white belt will know that thing. All Chinese medicine aside, that's the same "standing strangle hold" anyone can learn from plate 195 of Farmer Burns. Sheesh, I was expecting a blow to the head, liver, or spleen. "Dim Mak" can be as simple as a carotid artery attack. That's neither mysticism nor a secret. I learned Dim Mak from Randy "Macho Man" Savage. Apparently the will to kill is the difficult part, not the way to kill. Weapons and techniques don't really matter: a meat-maker is a meat-maker no matter chemistry or mysticism.
If you fancy an analogy, as I often do, give me a .45 and I'll show you the "flying pellet spin attack." It's a vital points attack to the side of the head. The temple of the skull has five lethal points.
Any strike to those points with the proper technique will result from a blow insufficient to dislocate an attacker's wrist. With time, proper breathing, and practice the flying pellet can be applied from fifty yards or more.
We can make some groundbreaking movies featuring the spinning pellet from horseback, which takes a lot of skill and technique. Tom "Sensei" Mix will be our first star. He's just a movie star, though. His flying pellet attack never faced competition.
Of course, real flying pellet masters don't advertise nor do they directly compete against each other. In fact, very few use the old Equestrian artifacts. The attacks are simply far too lethal to use in sports.
