Well, so this doesn’t necessary imply that our sense of smell makes us all somehow psychic. However, scientists think that elderly people can sense how many years they may have left in them.
In a 2014 study, the researchers stated that they aimed to ascertain whether olfactory impairment is a precursor to 5-year death.” They found that “a person’s likelihood of dying is even stronger when they lose their sense of smell.”
Indeed, according to this study, olfactory dysfunction is a more reliable predictor than “lung disease, cancer, or heart failure.” Whoa!
Lead author Dr. Jayant Pinto, an associate professor of surgery at the University of Chicago, stated in a statement published by Live Science: “We think [the] loss of smell is like the canary in the coal mine.” Although it doesn’t immediately cause death, it is a sign that something has gone wrong and that harm has been done.
The study examined “a nationally representative sample of older U.S. adults” in order to reach this conclusion. Among them were 3,005 individuals, ages 57 to 85, who lived in the neighborhood.
According to the study, the people were initially examined in 2005–2006, and in 2010–11, their mortality was ascertained. Five odors were given to each adult: “peppermint, fish, orange, rose, and leather.”
With at least four of the five scents correctly identified, 78% of the participants were classified as having “normal smelling abilities.” About 20% of respondents accurately identified two or three fragrances, while the remaining 3.5 percent were unable to identify any scent at all or just one out of the five.
However, it’s thought that “a diminished sense of smell may indicate what McClintock referred to as a’reduction in the body’s capacity to restore essential elements that are deteriorating with age,’ culminating in demise from other sources.”
Olfactory dysfunction “may be an indication of slowed cellular regeneration, or it may be the consequence of years of exposure to harmful environmental conditions,” McClintock continued.
How fascinating is this?
