Dr. Richardson, I am amazed at the amount of information you research, collect, parse, and assemble into something that is so brief (considering what you must start with and sift through) and understandable that even I can 'get it.' I reach this conclusion partially by looking at -- and sometimes following -- your MANY cites and sources. Several times I have imagined scores of student assistants or full-time staff devoted to your topic(s) of the day, maybe like a news staff working for a media journalist; else, how do you do it? I won't pry any further into professional professorial trade secrets. It is enough for me to know that you do what you do, and why you do it -- to our great edification. And through us the truth travels far.... With my greatest admiration and thanks!
