I did 5 years as an engraver in a mold and die shop for zinc and plastic parts in Philadelphia. Worked as a welder/sheet metal fabricator in Idaho, and did seasonal work for the forest service for some years. The operation was removing seedlings from the ground, inspecting them for quality, then packing them for the hoedads to plant in the forests.
I was making wood stoves and custom trailers (boat, utility) out of my garage when I threw in the towel and applied for disability.
I've had spinal problems from age 26. My mother once told me I fell 7 feet onto a concrete floor in the house my dad built (that didn't have stairs in yet to the basement). I was about 4.
