New research suggests that having four common bad habits can age you by 12 years.
The four bad habits are smoking, drinking too much, not getting enough physical activity and a poor diet.
The findings highlight yet another reason to adopt a healthier lifestyle. The study tracked nearly 5,000 British adults for 20 years. Of those with all four bad habits, 29 percent died. That compares to 8 percent of the healthier people who didn't have those unhealthy behaviors.
The study appears in Monday's Archives of Internal Medicine.
