Hah! Welding!
I once began an apprenticeship in welding, when North Sea Gas was happening.
I was praised for my beautifully symmetrical welds.
But I figured that there were better ways of living than being burned, torn, grazed, sprained and gassed, while wearing lenses so dark I was living in a burrow.
All while being paid so little that I starved.
So I starved, instead, without all the negatives.
Do I know what's what, or what?
