Of all the times of life to give up smoking, a recent study shows that on retirement is a great time to kick the habit. The research showed that a total of 42.5 per cent of those who had recently retired had quit smoking, compared with 29.3 per cent of those in employment and 30.2 per cent for those who were already retired. The results indicate those who undergo the transition into retirement are more likely to quit smoking than those who do not.
