[The tobacco's inconsistent properties]

Why do creative heavy smokers often persist with unsound and unsanitary attitudes? The group of heavy smokers express uncomprehensive and explicit behaviour in their stubborn way "it's not us" - just as some paintings with contradicting titles. A critical conclusion must be, however, tobacco can also supply with a regulation of thoughts and approaches in important social, cultural and scientific projects. This paper includes two suggestive cases selected from the scientific past in Denmark, displaying two famous and glorious personalities with the profound integration of smoking habits. Time has changed, however, and recent investigations now support the idea to fight down the lock of bad habits in heavy smokers. Thousands of lives can then be saved during the next 10-20 years.
