I'm at 2:21 minutes into the lecture and you're still informinig me on why it's good to know how people live. I already know that, that's why I'm watching the lecture. I know I risk coming across like I'm knit-picking you, but I really don't mean it that way. It's intended as constructive criticism. I watched one previous video, and the gentleman was statiing that a herder would have dung on his sandels from following the sheep and now you're saying he would be leading them.
