AR, quitting smoking as discussed in another thread is still one of my 'top five challenges' that I've faced and conquered and it can take a while before the time is right and the person is ready to quit.
Also, there are a lot of opinions and experiences here to help give a range of reactions and offer a fairly wide spectrum of data to mull over. I'd say that for the sheer numbers of people exposed to asbestos (or the number of exposures over time) compared to the number of people who contracted a condition, your odds of having a negative impact from this are pretty low. Your odds of learning a lesson are pretty high and that'll serve you well in a lot of ways.
