Hi, "face" - that's what the links are for. Every time I use a statistic or percentage or any other tidbit of data, I offer you the link to where that came from. I don't make it difficult to follow the breadcrumbs.

In my "day job," I'm an English professor, so citing is pretty standard, I just don't use MLA style, I take you directly to the water. You can drink if you want.
