The 11 obvious facts have been confirmed by science

There are things that seem to be "all-round, good-looking, random," but if through research, they exist based on very interesting scientific bases. The following 11 facts will prove to you.

1. Cats never "listen to" people

Cats really don't pay attention to what people "say" to it

Your pet can recognize your voice but in the end, he doesn't notice you at all. A recent study conducted at the University of Tokyo has shown that although a cat can recognize the requirements (by "commanding") the owner, they really don't care as much as we still do. think. So what is the reason it "ignores" you? The main answer is evolution. Unlike dogs - animals that are domesticated and nurtured by humans, domesticated "cats" should have no reason to listen to the master's orders.

2. Students who do homework will have higher scores

The more you work hard on homework, the higher the score

Economist Nick Rupp divided his class into two groups: one group was asked to do homework and the other did not. The results are very (or nothing) amazing. Hard-working students make essays delivered at home with higher score and average grades. Thereby, he concluded that "Homework has a great impact on student achievement at school".

3. Men pay attention to women's breasts

Men like women who own standard bodies

In an article titled "My Eyes are Up Here" , Sarah Gervais and her colleagues used Eye Tracking Technology to identify receive what they have long suspected - men like to glance at women's breasts. In fact, the men spend a lot of time watching the weaker body than the face. Their eyes will be "wandering" longer if the opposite girl has a big "round", slim waist and round 1 round. However, not only men, women's eyes are the same. Only thing, the weaker sex only looks for the purpose of comparing itself.

4. Wearing high heels will cause leg pain

High heels are not healthy

When wearing high heels, your posture will change, such as tilting your hips, although using it may make you feel taller and your gait is more flexible than before. Some evolutionary psychologists (Evolutionary Psychology) argue that wearing high heels is part of the fundamental push for the opposite sex. While this statement is still unclear, some other scientists claim high heels are not as good as we thought. A study conducted at the Institute for Research on Aging has found that 60% of older women suffer from leg pain after wearing high heels or dancing shoes for years.

5. Pigs like mud baths

Pigs bathe in mud simply because . like

Pigs do not have many sweat glands, so controlling body temperature is always a problem for them. Because of this, for a long time, scientists believe that pigs like to immerse themselves in mud to cool their bodies. Although that is true, a study published in Applied Animal Behavior Science has discovered an evolutionary transformation: Pigs do not roll in mud because they show There are a few sweat glands, rather, they have only a few oranges due to their "interests" immersed in the mud (in other words, pigs never develop sweat glands because of their ancestors. " rolling "in manure". Now, some scientists believe that simple mud bathing makes this animal happy.

6. Men go slower when walking with women they like

The faction is going slower when it comes to the weaker faction

Scientists at Seattle Pacific University confirmed that when couples go together, husbands tend to slow down. They will reduce the speed by about 7% while the wife will not speed up or slow down at all. However, when men walk with their friends - whether male or female, the pace of walking hardly decreases.

7. Grains are better when you have more milk

Adding milk, the grain will be more brittle

When adding water to small milled corn, scientists at the Chilean Catholic University (Pontifical Catholic University of Chile) discovered that intermolecular interactions in a "matrix" of corn chips can be weakened that "some components are dissolved and reduce mechanical consistency". Simply understood, water makes the cereal become flaky. Milk is different. The presence of fats will help the grain not absorb too much liquid, so they are still crisp.

8. Eating more will gain weight

Absorbing more calories will affect weight

From the 1970s until now, an average American weighs about 19 pounds. A 2009 study of the European Congress on Obesity found that "the weight of the American population can be explained by overeating calories" Boyd Swinburn - Research leader confirmed. Laziness has little to do with this phenomenon.

9. "Real life" meeting

Meetings cause time loss and work motivation reduction

A study done in 2005 conducted by Group Dynamics shows that meetings are "breakers" that waste time. By analyzing the notebooks of 37 employees working at universities, the researchers concluded that meetings made employees tense and grumpy, even hindering the most motivated employees to complete. into a mission.

10. Reading is good for the brain

Read books for brain development

Reading motivates the brain to work more to process information, analyze, solve problems and create emotions. So, if you are a book lover, congratulations and you, but if you don't have the habit of reading, start today.

11. Internet is what makes productivity decrease

Internet impacts productivity

The internet is a great tool with the power to make incredible things. However, according to Pew Research , 53% of people aged 18 to 29 online once a day just to kill time. Older people, this rate is even worse. Almost two-thirds of them spend their time surfing the web all day without a clear purpose.
