How many times where she argued with others about what the smell, some beautiful finds, as you find them repulsive and annoying ?! Do not worry, your problem is not around you who do not, there is a scientific reason behind it, its nuclear acid!

The sense of smell is a specific set of genes encoding system, and that each of us has different Ohmadh acids, each of which interacts with different scents in different ways, in the sense that we smell the same smells different ways! It's one of the things you notice them without thinking about it, some people prefer certain smells, but some find it disgusting!

To detect this, researchers from Duke University keeps track of why we smell the odor of different ways, and it turned out to be more complicated than just a matter of preference or not ordered. The researchers found that 400 gene is directly responsible for providing the source code for the Mtsagblatt smells in the nose and, when broken down into smaller molecules, there shall be more than 900 thousand sets of genes odors.
Another reason plays an important role in the different odors from one person to another, absence or presence of a single amino acid difference in the mean inhalation of odors. To find out the size of the differences that stand behind them and amino acids, the scientists isolated 500 receivers have 20 people, there was a slight difference between them, and in some cases the difference in a single amino acid.
After that, Almtsagblatt were exposed to minute amounts of different odors, it allows to follow any of these receptors interact with any of the smells, and thus show how each person received odor information differently.

 This does not happen only in the testing labs, when we smell something, the smell enters the nose, and hit the receptors, which in turn, supply the information to the brain, to tell us whether they are bad or good smell. And the presence of 900 thousand likelihood method programmable those receptors in our brains means the diversity of ways in which we receive the odors.
Visual receptors and their relationship to the olfactory receptors
There are plenty of differences between people, if they take two people and compared the way they interact with different scents you'll find that there are differences, including 30%. Has been similar this process the visual system, but to varying precisely, the differences in the visual receptors are working to change the way we see colors, this is what makes some people infected with color blind, applies the same principle to the sense of smell. Now you know why you hate the smells around you prefer?
