I had this conversation the other day about one of my old friends. He worked as a mechanic in his fathers garage for about 20 years, then took over the operation for another 20 or so years. I've been down there helping out now and then, and seen how he worked. Blowing brake and clutch dust everywhere, was an everyday thing. Spraying various cleaners and de-greaser's .without and mask or respirator. I've also seen him paint cars ans various parts without a mask, just his shirt pulled up over his mouth. It wasn't because he was too cheap to buy any type of protection, he didn't realize how the human body would absorb the chemicals into his body and effect him. I saw him with my own eyes wash his hands in gas everyday after work. I asked him why?, he said it's the best thing he's found to clean his hands after work. Once he sold his shop and went to work in the states garages, he started coming down with all sorts of illnesses. At least 6 types of cancers. He had prostate cancer when he was 41, and at that time they just removed it to deal with it. Then kidney cancer, lung cancer,had a spot on his brain they used radiation on. Several cases of skin cancer, and it was liver cancer that finally killed him. He spent his last years getting around in one of those scooters. His color was bad , and he always looked like he didn't feel good.Henry was a super nice guy and I'm glad he lived long enough to see his granddaughter. My thought on the is just because you expose yourself to harmful chemicals today and feel fine, doesn't meant it wont effect you years later. Like smoking, it doesn't kill everyone you just don't know how your actions will come back to haunt you when you get older.,,,
