People often do not think or think not enough about their health and the factors which can influence on it in positive or negative way. For centuries people like to do things that may harm their organism in some way absolutely consciously. People smoke, drink alcohol, use drugs etc. Most of such people think that millions of people which die from nicotine each year are very far away from them, people think that everyone else can die except for them. Indeed smokers begin to think about the harm of smoking and nicotine when their friend, neighbor or relative suddenly dies from a disease caused from cigarettes
