Related, I was struck by a comment made by the respiratory specialist doctor Martin Tobin, during the George Floyd murder court case. He said less than 10% of smokers actually go on to get 'issues'. He was pushing back on the line that as a smoker, George Floyd was more prone to react badly to 'having a knee on his windpipe...' you know the rest.
I did rewind and listen again then look up what he was saying and indeed, my assumed knowledge of smoking was altered.
Apologies for my vagueness with 'issues', I don't want to under or over state what he said and right now I can't locate the exact sentence within the days of testimony.
