jeez that's horrible, its funny how now a days people can't believe the stuff people used to use 20-30 years ago without protection and whatnot (varsol without gloves, coal mines with black lung etc.) just imagine what people are going to say in another 20 years about some of the stuff we do now a days. I work in a CNC machine shop, we machine so hard and hot sometimes it boils the coolant and steams us out of the shop, i can't imagine that stuff in the air being very good for us.
