It's all about the knife. It's ist nice and sharp, all you feel is a little tingling sensation followed by a slow but persistent darkening of suroundings and eventual loss of consciousness, a slow fall into abis. That's were the alcohol comes in handy, you will not loose you consciousness if you drunk and will get the full experience of blood slowly leaving your body, your limps getting nimb, you head light, "good" thoughts, euphoria....
So keep you knifes sharp kids!
Now getting shot is a whooooooole different and exciting experience.
