(Reuters) - Being unable to smell bacon frying may be far more dire than simply missing out on one of life's pleasures. In older adults, it could be a predictor of increased risk of death within five years.

In a study of more than 3,000 people aged 57 to 85, 39 percent of subjects who failed a simple smelling test died within five years, according to results published on Wednesday in the science journal PLOS ONE.

That compared with a 19 percent death rate within five years for those with moderate smell loss and 10 percent for those deemed to have a healthy sense of smell.

"Compared to a person with a normal sense of smell, a person with an absent sense of smell has three times greater risk of dying within a five-year span," Dr. Jayant Pinto, the study's lead author, said in a telephone interview.
