OK kids, try and follow me here. Above is the heading in big blue letters, OK? And on the next line is the word "(context)" with a flashing red box around it, see that? Well now click on that word "(context)" and it will take you to a whole new article! Isn't this fun? Now in that article is some additional information related to the stuff in this big black box above, and also within that new article are "links" in bright RED that will take you to more article, videos and information that you may be interested in. And you can READ these articles and WATCH the referenced videos. Sorry but some people keep asking the dumbest questions and are the same ones that are on the internet already and won't do a simple search for simple things. Pardon my frustration...............
