Tobacco

Many years ago the expression of caution outside the package of tobacco was very ambiguous. 'Be careful to smoke too much.' instead of saying 'Be careful not to smoke too much' Then people would often smoke not being cautioned properly.Now the caution was very strict. 'The possibility of lung cancer is twice to four times higher'Smoking exacerbate emphysema' ' It causes stroke' 'It cause angina'I never smoked but one day I felt like having just one then I stopped in front of the auto vendor of tobacco.I was overwhelmed by those cautions above.
