its good that someone has took the time to warn us all nice one 4 that, you don't take lung diseases lightly i knew a great guy 49 years old die of oesophagus's cancer that got on to the lungs, what a way to go you know that silage smell on motorways when your driving that was the smell coming from his mouth he couldn't swallow anything he had a tube via his nose, he constantly was spitting a dark brown liquid it was a true nasty time for those who loved and adored to watch, this wasn't caused through the workforce, they said it was a lifestyle what a price to pay so when some one takes the time to warn you don't wait till the government puts warnings out do you think they will for a minority such as us not a chance, yer you do what you want but if you think about it at least we know about it know as we never before nice one for that
