Swiss researchers looked at the health risks of poor diet, irregular exercise, smoking and high alcohol consumption among 16,700 Swiss men and women. Smokers were most likely to die prematurely, but people with all four risk factors were 2.5 times more likely to die. However, people free of all risk factors could increase their life expectancy by up to 10 years.
