I'll happily share what I know with anyone willing to listen.
But when I experience stuff like my wife's aunt saying (in all seriousness and between coughing her ringpiece up and taking another drag on her fag) "don't come near me with that thing, my doctor told me it gives you popcorn lung and I don't want that".
Well, you just can't fix stupid - especially when the stupid is backed up by a medical 'professional'.
And nobody with any influence will care what I say or think either, so I'm shit out of luck there too.
And if a smoker doesn't want to listen to me I'm like hell going to argue about it or try to change their mind.
So yeah, not my job.
It's the industry's job, it's the healthcare system's job, it's the government's job.
