Seniors may soon have a "smell test" when they see their doctor.
In fact, older people with a weak sense of smell have an increased risk of premature death.
A new study from Michigan State University examined about 2,000 seniors who were asked to identify 12 common smells.
Smelly, otherwise healthy people were almost 50% more likely to die within 10 years than those who had a good sniffer.
The study was conducted by researchers at Michigan State University and published in "Annals of Internal Medicine."
