Discover true love by yawning

Researchers have unveiled a simple but incredible trick that can show just how much your partner really cares about you.

According to researchers, the nature of yawning can reveal many things about the state of love. If one of the couple yawns and the other does not quickly yawn, their relationship may have many problems.

Science writer Sam Kean believes that yawning can help identify true love, because people are not "infected" yawning until they are 4 - 5 years old. This implies, we first need to develop certain areas of the brain, which may be related to social skills and empathy.

"Yawning contains a lot of information about neuroscience. A lot of animals yawn, such as snakes, dogs, birds, turtles, monkeys or chimpanzees. It is an extremely common reflex. However, in humans "Yawning can yawn and yawn and spread that action," Kean wrote.

In his book entitled "The Tale of the Dueling Neurosurgeons" , Mr. Kean mentions the idea that you can know that someone no longer loves you by determining their response time to yawn. .

In a 2011 study, Italian scientists observed more than 100 women and men from four different continents when they worked, ate in a restaurant and sat in the waiting room. When one of the volunteers yawned, the team found that anyone within a 3-meter radius would "yawn" and take the same action within the next 3 minutes.

According to survey results, race and gender do not affect the spread of natural urges about yawning. Even so, the level of intimacy between two people has a great impact. Specifically, yawning spreads more quickly from people who start to "infected" people when they have a close relationship. The time gap between the initial yawn and the yawning response between acquaintances will be shorter than among strangers.

This discovery means that the closer you are and the closer you are to the person, the faster he / she will respond to you.

Other studies have shown that people who are contagious to yawning are also good at looking at the thinking side of what others are thinking.
