I am an industrial technician which includes electronics, mechanics, and machine work. I no longer wear my ring since I got it between an auto type battery and ground then getting it caught in machinery guts several times, and nearly pulling my finger off a couple of times. I figured I could leave it off rather not having a finger to wear it on. It is on a chain around my neck when I am not working.
I have been married for 61 years and have not worn my ring for at least 50 years due to my job. I caught it between a car battery and ground one time and after I recovered from that I restored the ring an started wearing it again. Then I kept getting it caught in the depths of the machines I was working on and nearly lost a finger so I do not wear it. I probably should wear it on a chain around my neck!
