Well, after a few decades working in biomedical research, and then in IT stuff, I went back to a trade school and learned how to machine stuff. One of my first jobs was in a small company that did a lot of sheet metal work. So some of the activities in that video are not completely unfamiliar. But where I worked was doing larger stuff, not to mfg cook tops. And of course the workers would suit up better than the gentlemen in the video - with hand, eye, foot (steel toed boots) protection, and sometimes even leather aprons etc. The pace of the work in the video was also quite insane, but evidently the result of making the same product over and over. I got a kick out of the rags wrapped around one guy's legs to protect against getting sliced open by the semi-finished sheet metal. And I'm a bit surprised the workers seemed to have all their fingers and toes, LOL. Hey, it's a living, right?
