I can't seem to find any info on whether or not the risk disappears if/when you give up drinking. Or is the DNA roulette wheel already spinning, like it is for people who have been heavy smokers in the past?
I think it's going to be harder for people to take on board the idea that any amount of alcohol is bad for you as, intuitively, I still believe that, in moderation, it can have some positive affects such as de-stressing and aiding sleep. Mind you, I suppose you could say some of the same about smoking and I can intuitively accept that any amount of that is bad for you.
Well, I've never smoked [tobacco] and [apart from a bit of a 'sociable relapse' over Christmas] haven't drunk for over a year now. So I should live forever!
