This is the problem with questions here on Quora. There are many that are stupid. I hate to say it but it is very frustrating. What people do not understand is that you have to KNOW something to ask a good question, that takes research, thoughtfulness, and a bit of humility because you have reached a point where you do not know and are asking for help understanding. Questions, like this are in my opinion sickening, because they just waste our time even looking at them so we decide not to answer them. Or we spend our time complaining like I am doing now.
