The researchers started a study in 2003 to look at what makes people live past 90.
They say participants in their study who drank moderate amounts of alcohol or coffee lived longer than those who abstained from either drink.
In addition, people who were overweight in their 70s lived longer than people who were normal or underweight in their 70s.
