As we age we become less productive, less valuable to society. Nature has ways of eliminating us tares. I was priming a part in my paint booth. I got out my 3M mask and my 6001 cartridges I keep in a ZipLoc bag to protect them. I put on the mask and started painting. I noticed the filters weren't working at all, started bad-mouthing 3M for crappy product. When I finished painting, I went to my counter to clean my gun and there were the cartridges laying on the counter top where I left them. I shouldn't be allowed alone in my shop.
