Addendum -
My "worst" early job was loading tires.
Hot Atlanta summer, non-air-conditioned warehouse, dark and dirty, loading tires into railroad cars (which are all metal, of course, in the same sun).
The first ones were not so bad, but we had to stack them to the ceiling. I was taller than all my co-workers, so I was the one who had to toss all the highest ones.
After that, "steel-belted radial" was not an entirely positive phrase for me.
