I'm going to be real with you...I don't have my original script or any of my notes/resources/books/papers for this episode since I made it 5 years ago. I lost a lot of my scripts and work-in-progress writings the beginning of 2016 and this video was one of them. Very sorry I couldn't provide sources so you could explore more. I will, however, leave you with a link to the book I mentioned "Stuff Matters" because it is fantastic!
