I think you've misunderstood me, Kureha. I don't think you should take a knife out with you. When I said a person should act, I meant that in the situation where a car was coming toward them at a high rate of speed. The act is jumping out of the way. I don't advocate carrying a weapon.

Moving like a ninja sounds like fun. But please leave the knife at home. I'm afraid you're going to end up in the hospital.
