The mind is no longer the only element that reveals the level of people's intelligence. In this report published by the Australian edition of the Readersdigest magazine, Ashley Lewis points to other parts of the body that can also reveal how smart you are.

Researchers from Brown and Princeton University conducted a study in which they indicated that taller people may earn more money than short people, because they are smarter.

The researchers used government data that included people born in the United States or the United Kingdom between 1958 and 1970 considering their height, weight, intelligence, educational experience and salary.

The results of the comprehensive analysis showed that those who were tall in their childhood performed significantly better on cognitive tests.

Taller people also tend to work in jobs that have higher salaries and require greater intelligence and more advanced verbal and numerical skills.

Although researchers have yet to discover the relationship between height and intelligence, they suspect genes or upbringing may play a role as well.

The fact that you are left-handed does not necessarily mean that you are a genius, but it may have more cognitive advantages;

In a small study at the University of Athens, about 100 students and graduate students, half left-handed and half right-handed, took two cognitive tests: the first involved creating a path through a set of circles as quickly as possible, and the second involved a sequence of numbers and letters.

The left-handed people performed better than the rest on both tests, indicating that their memory is stronger and mentally resilient.

Some experts believe that these cognitive abilities are because a left-handed person can use both sides of the brain more easily to process information.

Body fat percentage affects many aspects of overall health, such as blood pressure, heart health, and possibly cognitive function as well.

In a 5-year study of more than 2,200 adults, researchers found that people with a BMI between 18.5-24.9 remembered 56% of the words on a vocabulary test, while obese participants (BMI of 30 or higher) remembered 56% of the words on a vocabulary test. Only 44% of the vocabulary.

The latter group's recall rate dropped to 37.5% when they were retested after 5 years.

Dr. Maxime Cornu - the study's lead author - hypothesized that fatty hormones can damage brain cells, and that another explanation for this cognitive decline is "the risk of obesity on cardiovascular disease due to the thickening and stiffening of blood vessels, which also happens with the arteries of the brain."

a big head

No one wants to be called a "big head," but it turns out that having a big head can literally make you smarter.

The Journal of Mullaklar Psychiatry published a study that included cognitive and physical assessments of more than 500,000 people in the United Kingdom, as well as examinations of blood, urine and saliva samples.

Researchers have found that people who had big heads as children scored higher on tests of numerical reasoning and were more likely to earn a college degree.
