Can You Pass the Longevity Test?

No one can predict with absolute certainty how long you'll live; but there are certain factors that may provide an indication.

For instance, your ability to smell may actually give a hint, according to the results of a new study published in PLOS One.

Researchers found that older people with an impaired sense of smell were more likely to die within a five-year period.

In the study, researchers tested the olfaction of roughly 3,000 older volunteers aged between 57-85. These volunteers were interviewed at their homes and asked to identify five odors (rose, fish, orange, peppermint and leather) that were in felt-tipped pens. The results were rated by a total loss of olfaction, some decline, and normal function.

Five years after the study was conducted, the researchers examined the mortality rates of the volunteers.

Researchers found 39 percent of the volunteers with no sense of smell had died, compared to 19 percent of the volunteers who had a decline in smell, and 10 percent with those who had normal function.

What are some tips to help improve longevity?
