On average, smokers in the UK smoke eleven cigarettes a day . If we apply that to the model confirmed by the BMJ, then, we see that smokers lose around two hours per day, or roughly thirty days a year. Conversely, when applied to ex-smokers, the maths show a more positive outcome: Every twelve years, non-smokers can extend their life expectancy by one year.
Today is the awareness day for a condition I have lived with for around 17 years called Chronic Obstructive Pulmonary Disease (COPD). COPD is a life-long condition that makes it difficult to empty air out of your lungs because the airways have been narrowed. Though you've probably never heard of it, around 1.2m people in the UK are diagnosed.
