That’s amazing. Just as some people are susceptible to things, others must be immune. My mum’s dad was a welder and so was also constantly exposed to asbestos for decades (although not to the same extent as the guy you knew), plus he smoked 20 woodbines a day, but lived until he was 76 and died of natural causes.
Yep. Fags. I used to smoke, packed in years ago. They do some people in and, as you say, some people are immune…
