I always disliked David Hockney for his campaign against the Smoking indoors in public places ban, probably the best thing the then sensible Labour government did for public health and predictably the Guardian supported him - that rag is always on the wrong side of history. No doubt he would have lived longer had he had any sense. That legislation brought in stop smoking clinics, trained smoking cessation counsellors and inspired stop smoking aids like nicotine replacement therapy. Probably the biggest positive change in public health since sewers and soap. One selfish old man with no children did his level best to interfere, we should not deify him.
