Every generation has some product/ingredient that they didn’t know was dangerous at the time: tobacco, lead, asbestos, etc. What is that item for this generation?
Yep. I worked a cnc table cutting fiberglass fabric for sailboat manufacturing. I was told the mask or ventilator thing (had filters and they tested it with smelling salts - I don't recall well) was only required when it was cold, because that apparently made the fiberglass worse for you. And that requirement was really just a suggestion.
