<<      I think that is a good rule. In my country, smokers are also prohibited to smoke in public areas. Tobacco has many harmful substances to human bodies. If they smoke in public areas, non-smokers' lungs are also damaged by indirect smoking. Smoking is not still strictly prohibited in my country. A restaurant which I used to go allow us to smoke. I don't like this. Medically, it is said that people will shorten their lives for 5 minutes and 30 seconds per one cigarrete. So I think it is a good rule to prohibit smoking especially in public areas.      Nicotine is a famous harmful substance contained in tobacco. We know that from variety of media such as newspapers and television. But tobacco has more harmful substances which directly damage our lung and trachea. Surprisingly, tobacco has more than 4000 harmful chemical substances. Those substances damage the smokers' lungs. At the same time, it also damage the lungs of non-smoker by indirect smoking. So I think smoking should be strictly prohibited in public areas.      In my country, many public places prohibit smoking. But we still have some smoking free areas even in public places. For example, my favorite restaurant allow us to smoke while eating. Of course smokers don't smoke while they have dinner. They smoke after or before their dinner. For smokers, that must be happy and that would relieve their fatigue during a day. But for us, non-smokers, we must smoke indirectly while we eat our dinner. I don't mind smokers smoke in outside area such as station platforms, but I don't like them to smoke especially in a restaurant.      Smokers must understand that cigarret surely deprive their health. Recently I learned in a lecture that smokers shorten their lives by 5 minutes and a half per one cigarrete. If they somke 24 cigaretts a day, they will shorten their lives for 2 or 3 days per month. By these statistics, smokers must know that smoking is no good for their bodies. So they must stop smoking at least in public areas.
