Another ignoramus. Are you really THAT unaware of the massive disaster asbestos has and still inflicts on regular people?
It was used commonly about everywhere. Asbestosis develops in about 20 years time so basically anyone of us can still get it. Anyone who worked with industry or did any kind of renovation at home is at serious risk to get contaminated. Not to mention cars brake pads were made of asbestos for decades. Ever changed brakes huh? A bit dusty eh?
Asbestos was used in fire retardant clothing, several cements for building, cooking plates, brakepads, insulation of several sorts (spray asbestos, bushings, plate insulators, tiles) They're still found in multiple homes all around the world. Thousands of industrial plants, military vehicles (been in the navy?) aeroplanes, boats, concrete. Pulverize anything that was made 1880 - 1980's and you may be exposed to asbestos. WTC was probably filled with the stuff. Inhale any dust there?
/Edit: Ahh you're from Canada. That explains it.
Canada has banned the use and sales of asbestos domestically but still sells it to third world countries. WTG!
People make asbestos products and pack them with no protective gear in places like India Pakistan etc. every day. Thousands have died and will die as a direct result.
