Older people’s smell exists and appears sooner than you think.

He old man smell It exists, but it has nothing to do with hygiene or the taste of Dandy Male. This conclusion has been reached by studies conducted by many scientists in recent years. Some people think that the fact that older people have a different, slightly unpleasant smell is a superstition, but there is a scientific explanation for this.

The key is in 2-nonenal, a substance that is formed as a result of the oxidation of fatty acids in the lipid barrier of cells. This topic is being discussed a lot on social media after radiologist Dr. Ena Mondragonhe will explain it in his account TICK Yes.

According to the doctor, this is starting to happen. from 30 years old, but over time it intensifies. We may find it unpleasant, but we shouldn’t criticize it because ultimately we all smell like that. At least this is the best that can happen to us. Of course, the smell of older people is different from person to person, mainly because no two people smell the same.

Our scent is more unique than a fingerprint

In 1976, a scientist from the then Soviet Union, Abram Ilyich Vinbergfounded what might have been the first odorological laboratory in the world. Specialists from various disciplines, one way or another related to the sense of smell, worked there. They studied the best methods for extracting scents from crime scenes and used them to identify possible suspects. They also worked on training dogs to recognize these types of odors.

These scientists noticed that every person has your own scented print. This is due to the set volatile chemicals, excreted through sweat and breathing. They are usually the result of the metabolism of bacteria living in your body, especially on the skin. Thus, the bacterial population is critical, as is the diet, environment, or medications a person consumes. Each of these factors provides the bacteria with its own substrate, so the resulting products are unique. Genetics also plays an important role. So we can conclude that identical twins will share a common scent. However, if they grow in slightly different conditions, their smell can vary greatly.

As for fingerprints, although until recently they were thought to be unique, in 2014 it was shown that they are not so unique after all. They can differ on different fingers of the same person and even be very similar between different people. So scent trace may be a much more important factor when it comes to identify the person. And if each person has his own scent, then the smell of older people will be different with age. The common factor is that it usually smells somewhat rancid, like bad oil. Since it is formed by lipid oxidation, this is a good comparison, but let’s look at what causes it.

Origin of the smell of old people

cellular oxidation This is a completely normal process in our body. This occurs when, for certain reasons, an atom loses an electron from its last shell and, in order to regain it, steals it from any nearby molecule. This molecule, for example, may be one of those that make up DNA, so losing an electron will be harmful. Thus our own cells produce antioxidant substances compensate for the effect of oxidation. The problem is that there are factors that cause oxidation to occur too much for the antioxidants to cope with. This happens, for example, due to habits such as drinking alcohol, smoking or unprotected sun exposure. Moreover, as we age, oxidation increases and fewer antioxidants are produced. Thus, oxidation is a clear marker of cellular aging.

loss of antioxidants This starts to happen after age 30. At this stage we also produce more lipids. Consequently, there are more lipids to oxidize and fewer antioxidants to prevent this. This means more release of 2-nonenal, which is responsible for the smell of older people. This odor is usually not noticeable in your 30s, but will become easier to detect over time.

Therefore, this has nothing to do with hygiene. Moreover, the perfume does not completely cover it, so there comes a time when its presence is inevitable. But as we’ve already seen, it’s a sign that we’re getting older, and as long as we’re in good health, aging is still a gift. Smell is the least important thing; but, in any case, we will not exclude that in the future science will find best perfume to cover it up.
