Bad habits could age you by more than a decade.
Researchers in Britain followed a group of people for 20 years.
They looked at four risk factors -- including smoking,
drinking two alcoholic beverages a day,
exercising less than two hours a week, and
not eating enough fruits and veggies.
30-percent of participants with all four risk factors died during the study--compared to just eight-percent of the healthiest participants.
People were an average 44-years old at the beginning of the study.
