Very Interesting. Thanks for the overview. I have done a lot of construction work and the average person doesn't realize how much thinking about different factors and outcomes can can go into even the seemingly simplest of jobs. I have often worked for people with college degrees that look down on someone who works with their hands but can't grasp the basics of the physical world. I had a job once where someone who was making way more money than me wanted me to change a light bulb in their living room. I grabbed a chair and changed the bulb. The task was beyond their problem solving abilities. Best of luck to you.
