If the 2 men that died from what was thought to be caused by por 15 were autopsied by 5 different doctors, each one would probably come up with different causes. Verde would probably be right.
Sounds like the disease that killed two people in our church several years ago in Calif. A third lady had it now in our church here in Texas. None of them were/are gearheads, previous two were a 70 yr old lady and a 60 yr old gentleman who never worked on cars. Current case is a 6o yr old lady. Symptoms of the disease are steadily decreasing lung capacity until suffocation. Takes only a few months after diagnosis.
When I was a kid (6 or 7) in the 50s living in central Calif, we had an asbestos pit in the back yard. Dad did some asbestos mining and I guess that's how we ended up with the pit. My sister and I loved playing in the pit, the asbestos was nice and soft and fluffy!! And I chewed lead pellets as a kid. And I loved playing with mercury from broken thermometers. 75 and still going strong. Just hope I don't die of anything serious!!
