While watching people do crazy and dangerous things can be fun, you also have to think about the person. I personally like to think about their motives behind it. Like people who do extreme sports, many do it to feel free, at peace with themselves, I find that admirable and would never try to take that away from them. However, this game here, the knife game, I don’t see what people gain from it? It appears to me to have no value passed bragging rights that your were able to do it without bleeding, at the risk of a trip to the hospital and possible permanent damage to the hand. So no, I don’t think this should be done.
