Do you have the potential of

The following signs will help you recognize who is smart from an early age.

>>>8 research on intelligence helps discover the mysteries of wisdom

How to know if you are smart? Do you use complex IQ questions or measure brain activity? Those expensive and time-consuming tests are in fact not the only solution.

Many studies have shown that just a few simple signs of your body or lifestyle can confirm that you are a superior person in your mind.

Let's see which signs can signal a intelligence above normal:

1. You are the eldest in the family

Did you know, the eldest child is usually the smartest, which is not dependent on genes. A study published in the New York Times showed that the eldest son often had 3 points higher than his IQ - a small but remarkable number.

The reason given here is not related to genetics. According to research, the main reason is the psychological effects from parents, including expectations from parents that the oldest child is always the most knowledgeable and needs to care for the children.

2. You are breastfed

Mr. Terrie Moffit of Kings London Academy and colleagues conducted a study on more than 3,000 children in England and New Zealand on the effect of breast milk on children's intelligence.

The results showed that babies who were breastfed had a 7-point higher IQ than normal if they had a special gene called FADS2 .

This gene is involved in the control of fatty acids. They can help children to best exploit the substances in breast milk and thereby develop better brain development.

3. You are left-handed

Left-handed people are said to be capable of 'divergent thinking' - a form of creativity when you have the ability to write an entire book just from a small inspiration.

Left-handed people often have the ability to create new things from seemingly unrelated objects. They possess a remarkable imagination, so they often do well in the fields of architecture and music.

4. You learn music

Many studies have shown that music helps children develop their minds in different ways. Psychologist Sylvain Moreno of York University conducted a study of the impact of music on children aged 4-6 by dividing them into two groups.

In it, one group will study music and the other will take a picture course. After giving a language proficiency test at the end of the experiment, the group of music students achieved a higher score. The conclusions drawn from the study show that music helps enhance 'language intelligence' effectively.

Another study conducted in 2004 found that 6-year-olds who learned piano for six months had a stronger IQ than those who took other courses.

5. You have a slender body

A study conducted in France on 2,200 people to determine the IQ has confirmed this. Accordingly, the waist measurement is inversely proportional to your cognitive ability.

Results from the experiment showed that those with a BIM of 20 or less could memorize 56% of vocabulary words in a test. Meanwhile obese people with a BIM index of 30 or more can only remember 44%.

Overweight volunteers were also reported to have a higher rate of cognitive decline after 5 years of follow-up. Their ability to memorize reduced to 37.5% of vocabulary while those with balanced weight preserved their numbers. It can be said that a healthy body really means a healthy mind.

6. You raise a cat

A new study by US scientists has shown that dog lovers will be more extroverted while cat lovers have higher scores on smart index tests.

One way to explain this conclusion is that dog lovers will often go out, take their dogs for a walk and communicate with people. For cat lovers, they are often introverted, sensitive and tend to stay at home reading more books. Therefore, they will be more intelligent.

7. You do not smoke

A study done in Israel proved this. They collected IQ of 20,000 teenagers both smoking and non-smoking.

The results showed that, on average, people aged 18-21 smoked would have an IQ level of about 94, while those who did not smoke were 101. , this number drops to only 90.

When comparing between blood brothers, non-smokers are always smarter.
