Re: A little social note..
Spike, I think your comment is a bit patronising - I would guess you are under 40.
as one of the "older people" ( > 50) I would say that smoking in pubs has kept as many older people away as it has attracted, maybe more. Naturally, they are not going to start going to the pub the day after the ban came in, but I don't think the pubs are going to be seeing their old regulars staying away in droves either. I am sure some miserable old buggers will complain about it, but then some people are only happy when they are miserable.
My parents were both heavy smokers. (20/day) My father gave up after his heart attack, but still spent his last year on oxygen, and my mother died of a smoking related heart attack last year. Neither went to the pub, because they couldn't stand the smoky atmosphere, the same reason I and my non-smoking wife didn't like going. I think the smoking ban is irrelevant here, and certainly non-causal.
Matt Kimber has the right idea, though it is a little harsh in parts; I am not sure I like over 65s being referred to as they/them - this assumes older people aren't like "Us". It is our choice (I include myself as I am much closer to retirement than school leaving) how we spend our money, and how we cope with the pressures of modern life.
I for one can't wait until I can afford to retire (70+ probably after being shafted over my pension for the last 40 years) and sit in the garden "sensibly" drinking a glass or two of wine while reading El Reg on my laptop.
Dr Peter Rice - sod off you whippersnapper, don't disturb your elders and betters when they are drinking.
