Dim Mak (Chinese: 點脈, “pressing arteries”) or Kyusho Jitsu (Japanese: 急所術, “vital point technique”) is the alleged martial art of striking specific points on the body to cause pain, paralysis, unconsciousness, or even delayed death (sometimes claimed to occur hours or days later).
Let's be clear: There are indeed vulnerable points on the body. But they work through known physiology, not mystical energy.
Une frappe mal maîtrisée sur un point vital (comme le sinus carotidien) peut entraîner des complications cardiaques ou neurologiques graves.
