Say I don't change the oil in my car. Have I not cursed myself to have engine failure?
a. An appeal or prayer for evil or misfortune to befall someone or something.
b. The evil or misfortune that comes in or as if in response to such an appeal: bewailed the curse of ill health.
You again have no idea what the hell you are talking about. You just throw words around with little knowledge of what they really mean. If you don't change the oil in your car you simply allow the chemistry and physics that go along with dirty oil to work it's affects on the engine. It has nothing to do with the definitions of a curse. Amazing.
