I remember as a Junior Neurosurgery Resident I admitted a guy with mesothelioma who had worked as a guy who sewed fireproof gloves for 30 years. We had a sort of epidemic as ship workers (Steve McQueen) who had been exposed to asbestos years before began to get it. Asbestos fibers are less than 5 microns.
Well, I guess thats it for today. I have to say, I was a little reluctant to do this because I thought I might get swamped.
