I worked on circuit boards mostly. One day I noticed a kind of buzzing in my guts, like an overloaded inductor. A couple of weeks later I noticed it again.
The buzzing got louder and louder. I needed to stay in my job long enough to fulfill electrical registration requirements, so I left the same day my ticket came through.
It might be something about the electricity that f's me up with computers. I do know I keep much better health away from them.
I'm writing this on a phone - for some reason that doesn't hurt so badly.
I can design algorithms, write stories, investigate questions in Physics or Chemistry etc quite well - for as long as I don't try to do it with a computer.
As for now, I find I'm better off, in myself, doing quieter work.
