From my perspective, I do not believe about superstition. Everything will happen from our performance which is the most important factor that affects to its result, so it is not appropriate with the superstition. If people always think about their eyes twitching, it will affect their thinking and their behavior. For example, if they have a right eye twitched, they will believe that they will have bad luck, so it is not good for people to determine that because they will judge everything that they want to do to be a bad thing.
