scoser's Journal: Computer Lung

I had the great idea of dusting out the inside of my family's computers, which had probably not been dusted out for at least a good year. While the dusting out seems to have done wonders for case temperatures, it was the devil on my lungs when I first pointed the can of compressed air at the CPU fan. This all leads me to wonder, is it possible to get Computer Lung from dusting out too many uncared-for computers?
