Well I worked in the Volkswagen stamping plant for years we started working on doors from Germany that they had a problem they couldn't fix I went back and fixed the problem and got to work on the oven where they baked the polyviral chloride we would bake the doors at 480° to cure this PVC that look like caulking white caulking when it come out of the oven it had bubbles on it here and there so I fix that problem but those doors were smoking like they were on fire when I came out of there and I had to get right next to them immediately with them smoking like that I was breathing that for years it didn't affect me till later on in life and now it's killing me I can't hardly walk I can't walk down my steps I'm a prisoner in this house what a life
