1. Monogamous love exists
Some psychologists tend to believe that a person is polygamous on an instinctive, natural level. However, if you observe the world of fauna, you will notice that some species of mammals choose their only partner for life. For example, monogamy is present among animals such as gibbons, swans, wolves, albatrosses, and black vultures.

2. Sympathy is born within the first 4 minutes of dating
Love doesn't start right away. However, sympathy for a person always arises at the first meeting, namely during the first 4 minutes of communication.

3. Lovers' hearts beat to the beat
When lovers look into each other's eyes, their hearts surprisingly begin to beat in time. To date, scientists have not been able to scientifically explain this phenomenon.

4. Love acts on the body like forbidden substances.
Feelings of a person in love are almost identical to the euphoria that comes from a dose.

5. Love replaces painkillers
It has been proven that hugging and touching a loved one can reduce pain. This is due to the fact that at this moment a special “pain-relieving” hormone is produced in the brain.

6. Couples who look the same are less likely to fight
Numerous studies have found that couples with a certain similarity in appearance live a stronger and happier marriage than couples with the opposite type of appearance.

7. Couples with the same level of emotionality and temperament are unlikely to be together
People who have the same outlook on life, as well as preferences, start relationships very easily. However, according to psychologists, it is difficult for partners with similar characters to build a serious relationship, because sooner or later they will get bored together.

8. Grief exists
Experiencing a love tragedy, we often resort to a beautiful metaphor: “heartbreak”. In reality, the heart, of course, cannot burst, but thanks to systematic experiences in the body, the production of certain substances that stimulate the work of the heart muscle slows down, which makes the heart ache with real pain.

9. Love lasts no more than a year
According to scientists, a person can be in a state of love for no more than a year. At the end of this period, he either moves to a new stage of conscious love, or is disappointed in his partner.

10. Falling in love is like a mental disorder
Studies have shown that an interesting chemical reaction occurs in the body of a person in love - a sharp drop in serotonin levels and an increase in cortisol levels. Exactly the same reaction occurs in the body of a person suffering from mild mental disorders.
