Featured Article - Older non-smokers gain most from tobacco ban, study suggests: "A study in New Zealand showed that, three years after a smoking ban on all workplaces was introduced, hospital admissions for heart attacks among men and women aged 55-74 fell by 9 per cent. This figure rose [increased] to 13 per cent for 55-74 year olds who had never smoked."

This is really interesting research! It basically suggests that ~4% of all MIs in 55-74 year olds is caused by second-hand smoke in public places!
