TWELVE million adults in Britain smoke. About half of them will be killed by their habit.
The facts are well-known and it is not surprising that three quarters of smokers would like to stop. A million and a half will try to today - National No-Smoking Day.
Smoking increases the risk of heart disease, lung cancer and asthma. It causes dull skin and wrinkles, as it reduces the amount of oxygen getting to the skin, accelerates ageing and makes the skin look sallow.
New research from Norway says it increases the risk of suffering from depression.
Many smokers believe cigarettes help them cope with stress but research shows anxiety levels actually decrease after giving up.
No-Smoking Day can help concentrate the mind and stiffen the resolve but stopping is said to be harder than kicking a heroin addiction.
But it's worth trying for your health's sake and your family.
