Your Nose Reveals When You’re Going To Die

Your Nose Reveals When You’re Going To Die

Have you stopped being able to identify familiar smells? Then you may be about to die, according to a new study.

A group of scientists studied a group of over 1000 older people who weren’t sick or suffering dementia. They gave each person a test to see how well they could identify 12 familiar odours. Those with the lowest scores had a much higher probability of dying over the next year than those who couldn’t.

According to the journal Chemical Senses, where the researchers published their findings:

Olfactory scores ranged from 0 to 12 correct (mean = 9.0, SD = 2.2). In an initial analysis, risk of death decreased by about 6% for each additional odor correctly identified (hazard ratio = 0.94; 95% confidence interval: 0.90, 0.98). Thus, mortality risk was about 36% higher with a low score (6, 10th percentile) compared with a high score (11, 90th percentile). The association persisted in subsequent analyses that controlled for naming ability, disability, cerebrovascular disease, characteristic patterns of leisure activity, depressive symptoms, and apolipoprotein E genotype. The results indicate that difficulty identifying familiar odors in old age is associated with increased risk of death.
