Smoking costs a lot more than just what you pay for a pack of cigarettes. It significantly increases the cost of life and health insurance. And you'll pay more for homeowners and auto insurance. Add in various other expenses, and the true cost of smoking adds up dramatically over a lifetime --$86,000 for a 24-year-old woman over a lifetime and $183,000 for a 24-year-old man over a lifetime, according to The Price of Smoking (The MIT Press).
Another habit to quit: indoor tanning. There is now a 10% tax on indoor tanning services. As with cigarettes, the true cost of tanning -- which the World Health Organization lists among the worst-known carcinogens -- is higher than just the price you pay each time you go to the salon.
