I appreciate you are new postman pat, but do you remember, before the AB let you post your question, it advised you that your question may have been asked already, and it showed you the first ten of a batch of several dozen instances of this question being asked. It then gave you the opportunity to cancel your question - but for some reason you went ahead.
You should know that this is the most asked question on this site, for reasons no-one knows, hence the ire you have unleashed.
So now you know.
Apart from that - welcome, glad you could join us!
