I never do things like knocking on wood. The reason why I don’t is probably because it never became a habit to me, as it did to many people I know, both older and younger. I guess nobody really believes that it works, whatever knocking on wood might mean… It just became a habit to them, for example they learned it from seeing older superstitious people do it, who probably thought it worked. On the other hand, some people probably hope that knocking on wood or something else of that kind will prevent a bad thing from happening. However, if they actually tried doing something more than just knocking, there would probably be less of so called bad things and at least they’d feel they really did something to try and prevent them from happening. That would probably mean the total end of the ‘magic knock’.
