Sense of smell could predict death!

As people age, becoming less sensitive sense of smell. Based on the results of the study, more and did not recognize the smell of it means the end of the age is approaching.


Researchers at Rush University Medical Center in Chicago found it. The more sharp smell someone, their lifespan will be much longer. Difficulty identifying odors in old age is associated with increased risk of death.

Researchers gave volunteers aged 53-100 thousand standard smell test of 12 items. "We use the graffiti and the smell test, each odor in which participants have four choices," said study leader Dr. Robert Wilson.

"The smell is quite familiar, such as smoke, lemon, dark chocolate, pepper and cinnamon," he added. The researchers and participants who have no dementia or Parkinson's for four years. During this period, 321 persons or 27.6% died.

Amazing, researchers found the risk of death 36% higher for those who are only able to answer six questions correctly than those who managed to identify 11 of the 12 questions.

This association is true even when age, disability, depression, brain dysfunction and recreational activities are also taken into account.

"The results showed difficulty identifying odors in old age-related increased risk of death," said Wilson, in a study published in this journal Chemical Senses.
