Modern human sense of smell

Modern human sense of smell is pretty bad. People who can easy recognize thousands different smells are rare ones. It is because around us is a lot of artificial flavors, whose molecules deaden true smells. Our sense of smell is weakening also because of aging' changes, and because of the polluted air. That leads to fact that urban people sense is worse than those who live in rural areas. 

An enormous influence on the ability to smell makes our diet – not a pungent onion or garlic, but a fat makes problems for our sense of smell. That is what scientists have proved.

On the other hand, the smell has long been considered less important for human survival, and for its exploring, developing received less attention than vision or hearing. After all, we have very little words to describe the smell and borrow them from art and music. 

Some scientists say that people feel pheromones, others say that they can not be smelled. But that we can’t live with someone if we do not like his smell, I have no doubt.
