Aroma of the world

The world is full of smells that give us the idea of the essence of the object. Usually if the smell is unpleasant the object is bad and negative, but if the smell is pleasant, the object is usually good and beautiful. For example, flowers of the world smell pleasantly spreading their aroma all over them.
Everything in the world has its smell. And even the world itself has its smell, it is simply necessary to feel the smell. Tastes differ and some people like to smell the definite aromas while others consider these smells to be awful. Anyway we are surrounded by the smell wherever we go and whatever we do.
When we start to realize the world and everything that takes place in the world, we begin to pay attention to the smell of the objects that surround us and to our proper smell. And to hide this smell, people use different perfumes that give such variety of aromas that sometimes it is very difficult to choose the one.

But natural smell is not so bad as it may seem. As according to many scientists person's body emits the smell that attracts people of another sex. So, in fact nature made all smells we have including not rather pleasant smells simply to attract the representatives of another sex.
