'Small' findings help people 'live longer'

UHT milk, shoes, cotton . are historical findings that contribute significantly to increase the life of the human species.

About a century or more ago, human life has increased significantly. In the United States alone, the average life expectancy of Americans has doubled compared to 150 years ago.

Many people believe that this is obvious, the reasons given are numerous: it is due to vaccines, clean water, therapeutic methods, drugs against cancer .

But if that's the case, it seems like they underestimated the ability of humans. Through surveys and research, scientists have given quite a lot of odd reasons but contributed significantly to making human species more 'persistent' today. Here is a summary of some breakthrough "small" findings that help people enjoy life longer, according to Business Insider.

1. Cotton cloth (cotton)

In the past, typhus caused by Rubella virus was one of the most deadly diseases. For ancient medicine, the death rate of the infected people is very large.

Rash fever was also one of the reasons Napoleon's world's most powerful army suffered defeat in Russia in 1812. And the reason for the rapid spread of typhus outbreaks was lice. In the past, woolen fabrics were mainly used, but with difficult to wash and sticky characteristics, sweaters were the ideal place for lice.

Later, when cotton with a thin, easy-to-wash material was replaced, the lice did not have a place to live, from which the plague no longer had a source of spread.

2. Fluoride (fluoride)

In the mid-twentieth century, human medicine was not really developed. This causes many patients to die of dental disease. Many people believe that this is the worst death when an infected tooth makes the patient extremely painful, affecting the eating, the head hurts . And when the bacteria are ingrained in the marrow is when the family holds a funeral.

We can say, we are fortunate to be born when scientists have succeeded in bringing fluoride - a chemical that works to strengthen teeth, slow down the breakdown of yeast and enhance mineral supplementation in creams. Brush your teeth and mouthwash.

In addition, along with the advancement of dentistry, the treatment of dental diseases is easier than ever.

3. Pasteurized milk

Today, we have the phrase 'sterilized fresh milk' printed on all milk cartons. But just because it was not sterilized, but before the twentieth century, the mortality rate from poisoned milk was extremely high.

Tainted milk is the culprit that kills thousands of children, a source of typhoid, red typhus, diphtheria, tuberculosis and many other dangerous diseases.

One of the most successful health campaigns of humanity is the successful milk pasteurization in the late nineteenth century and early twentieth century. Thanks to that, few people in the twenty-first century know, milk can be deadly.

4. Botts score

Botts were invented by chemist Edward Botts. These are silver-plated metal spots or painted in floating and reflective colors, enabling vehicles to differentiate lanes when dark or bad weather, which we often see on the road.

In addition, the Botts points have uses that even the inventor did not expect, that when driving through those points will create a characteristic sound, with a slight shock. This "saved" countless drivers' lives when they fell asleep or neglected.

5. Shoes

Hookworm is a parasite that invades a person's body mostly through bare feet. They often punch through soft skin between the toes, causing itching and discomfort. Hookworms spread when people go barefoot through the feces of infected people.

The thong sandals (the forerunner of shoes) were born and used long ago by ancient civilizations. However, it was not until the 1950s of the nineteenth century that the sole of shoes with the design of the whole foot was really a breakthrough that helped protect human feet.

There are two layers for a shoe, a base to create an 'ultra-thin' shoe, and a piece of leather made by the shoemaker on the nose to create the necessary space for the leg if desired. The shoe looks more plump and firm. Along with that, in the twentieth century, education campaigns began to encourage people to build separate toilets and shoes to keep themselves safe, avoiding the risk of hookworm infection.
