In 1971 the Royal College of Physicians decided to take action on the problem of smoking and health. They formed an organization called Action on Smoking and Health -- ASH. Its aims are to make people aware of the dangers of smoking and to help those people who do smoke to give up. As part of its campaign to make people see how smoking damages us all, both as individuals and as members of society, ASH has gathered together some every convincing facts and figures. For in stance, smoking is very harmful to industry. Nearly 50 million working days are lost in Britain every year due to smoking -- at least four times the number of days lost in strikes. And the cost of treating people suffering from smoking related disease is around £ 100 million each year.But the human suffering which smoking causes is far more serious than the economic price which society has to pay. 95% of those who suffer from bronchitis are smokers. It has been estimated that 20% of all cigarette smokers become disabled by chronic bronchitis and may eventually die of the disease. Over 20,000 people die of bronchitis every year.Lung cancers kill more people than any other types; of cancers; 90% of them are caused by smoking. With coronary heart disease the risk of death is 2 to 3 times as great in smokers as in non - smokers and this disease is now the major cause of death in Britain.Bronchitis, lung cancer and coronary heart disease arc the three most serious reasons for not smoking but there are other masons which are also important. The message from ASH is clear -- if you do smoke you should give up now and if you don’t smoke then you should not start -- ever. Due to smoking, which of the following statements is NOT true()

A. Economic losses are the most serious.
B. Human sufferings are more serious than economic losses.
