They met each other, and immediately realized that fell in love. Does it happen only in novels?Does the love at first sight exist in real life?

Scientists believe that this feeling really can be just a fraction of a second. But why is this happening? What is this spark? There are several versions.

Version One. For posterity

Some experts believe that love at first sight occurs at the genetic level. Man can feel this emotion if he see in woman a potential partner for breeding and obtaining the most healthy offspring. The more successful genetic combination of men and women, the stronger feeling will be. First of all people see the appearance of each other, and if they like each other, they will continue to get acquaintance.

Version Two. Smell

According to this version, we are like animals, choose our partners by scent. Ostensibly the smell tells us to what kind of person you can live the whole your life in perfect harmony. However, you can use some perfumes. People have been using perfumes at all times – in ancient China, Egypt and the Roman Empire, for example, they mixed the odors for attracting a man or a woman. It was believed that the ladies attracted to the smell of cedar, patchouli and bergamot. However, artificial flavors are able to attract only for a while. The real attachment gives a natural body odor.

Version Three. The memory of the past

This version of the supporters of the theory of reincarnation. They believe that love at first sight occurs when we meet partners from their previous life. Such meetings are rarity, usually people who knew each other in another reality, can not meet each other in this life. However, if matches are still going on, there is the very sudden love. Usually, this feeling is very strong, and these meetings people remember forever.

Fourth version. Selfishness and self-respect

According to this theory, we are looking for ourselves in a potential partner. It is because of the external similarity to your own face, the features of the beloved one suddenly seem so close and enjoyable.
Sometime people who are long time together become similar to each other. And it’s the fact that people start to copy the speech and manners of the person with whom they live. Also it is according to taste in music, books, hobbies and so on.

Fifth version. Parents
Some experts believe that there is no mystery in love at first sight. People want to find someone who can be just like their parents. It is not necessarily to have a lot of common matches with parents – quite enough the coincidence of several traits.
