Some people believe lucky numbers so deeply that they will afford a telephone with numbers without four and others which is bad in their mind. they argue that the lucky-number really can bring good luck, and, at least, no evidence testify they can not.
As far as I am concerned, there is no such relationship betwwen the numbers and lucky, for the reason that numbers theirself are given certain meaning for the purpose of application of mathmetic. And, In addition, man should not depend on lucky which, in their mind, the numbers gives them.
