7 Weird Facts About Human Beings You Didn’t Know

You can be identified with your ears

The outer and most visible part of your ear can be used to identify you because it is unique to each individual, thereby making it a good means of personal identification. Although thumbprints and DNA are the more preferred options, the fact that former gets worn out over time and the latter is quite invasive has made using the ears as a means of ID become increasingly more popular. The shape of the ear is easy to map with computer software and it rarely changes over a person’s lifetime. Current technology can correctly identify an individual ear about 99.6% of the time.

Coffee drinkers live longer than non-coffee drinkers

Many studies have shown that people who drink coffee tend to live longer than people who don’t. Although scientists are yet to figure out what causes this bizarre benefit, research shows it exists. The benefit exists whether you drink caffeinated or decaffeinated coffee.

Laughter can kill you

As bizarre as this sounds, there are many people who have gone down in history as people who died from laughter (probably had one too many LMAOs). Laughing itself isn’t deadly, in fact, the saying that “Laughter is the best medicine” still stands, however, a laughing fit can place undue stress on the heart and lungs, which can lead to a heart attack or asphyxiation especially in a person that is seriously ill. It is a very rare phenomenon, so the health benefits of laughing far outweigh the risks

Children Can Learn Between 4000 – 12000 Words Each Year From Reading Books

One study showed that children can learn up to 12,000 words per year from reading books alone. The average child will pick up around 2000-3000 words per year from their normal education. This amount increases dramatically if the child reads independently, even for as little as ten minutes per day.

The More Creative You Are, The Longer You Live

A study has shown that being creative is actually linked with living a long life. In fact, the study shows that the more creative the person, the lower their risk of death. Many scientists are of the school of thought that it’s because creative people tend to use their brain more through creative thinking, thereby keeping the brain healthy.

 

Plants Help Humans Increase Concentration and Creativity

Many studies have shown that people who are working or studying will have increased levels of concentration when they can see plants from their desks. This seems to be related to another finding, that concentration can be improved by exposure to natural environments. One theory to explain this might be that people take unconscious micro-breaks to look at the plants and inadvertently refresh their ability to concentrate on other tasks.

Only 2% Of The World’s Population Have Green Eyes

Green eyes are considered to be one of the rarest eye colours in the world. This eye colour is very common in people with North and Central European descent, and a few others from the Middle East and Asia. While eye colour was once thought to be controlled by only one or two genes, scientists now believe up to 12 genes influence eye colour. This can make it difficult to accurately predict what eye colours people might inherit from their parents.
