Annual health care costs are roughly $96 billion for smokers and $147 billion for the obese, the government says. These costs accompany sometimes heroic attempts to prolong their lives, including surgery, chemotherapy and other measures. But despite these rescue attempts, smokers tend to die 10 years earlier on average, and the obese die five to 12 years prematurely, according to various researchers' estimates.
