Having a keen sense of smell may predict a longer life.

Researchers in Sweden asked more than 1,000 40 to 90-year-olds to identify a variety of odors.

People who could not smell at all were 19-percent more likely to die within 10 years, than those with normal smell function. 

Each correctly identified odor lowered the risk of early death by 8-percent.

Experts say a bad sense of smell does not cause death, but could signify an underlying health problem.
