Have you worked in shipyards before? Then you are at risk of asbestos exposure
There are certain jobs that increase one's risk of asbestos exposure. If you worked in shipyards during World War II and the Korean War you were very likely exposed to asbestos. The material was greatly used for shipbuilding because of its ability to resist corrosion and high temperatures. The asbestos dust tended to build up around these areas and other inadequately ventilated parts of the ship, which led to human exposure aboard vessels. Not only the shipbuilders, but the crews of those ships and the longshoreman (those who load the ships) were heavily exposed to asbestos as well. In fact, before the 1980s, many longshoremen probably even loaded bundles of asbestos onto ships. Before that time, the health risk associated with asbestos was not known by these workers and no special precautions were taken to prevent inhalation. A scientific study revealed that 86 percent of shipyard workers with 20 or more years of experience developed asbestos-related lung disease or lung cancer. I...
