Arye, welcome back. I’m glad your trip was safe. The “screw” you are referring to in your rollator is a bolt. The thing that holds the bolt on is a nut. A screw is also threaded, but clings directly to whatever it is screwed in to without needing a nut.
Another beautiful fall day here in the desert. 74 at the moment, and forecast to be around 90.
Mark, there was a Heinlein story that had brand new cars that were made for the express purpose of being crushed and recycled. It kept people employed making the cars and other people employed crushing them. Of course, he never addressed the economics for the companies that were making no profit. (Pay to make the car, then pay to have it crushed? or does the crusher pay the manufacturer and then get paid in turn by the recycling company?) The novel was “Door Into Summer” and is one of my old favorites.
Good morning, Vagabonds.
