3 scientific discoveries about people make you surprised

The way of life can also change genomes, human beings are not special creatures . surprising scientific discoveries for many people.

If you think that death from loneliness is only a matter of fixed age or genetics, the following scientific findings will show you the unexpected truth.

1. The way of life can change your gene system

Each of us inherits a particular set of genes but the results of that inheritance are often not fixed. Our environment, our diet, and the circumstances surrounding us can also make the genetic system change.

Translation studies in the small village Overkalix in Sweden show an interesting situation. This is a village near the Arctic, most people depend on nature, so the year is really hungry, the year is abundant depending on the harvest. However, the special feature of this village is the birth, genealogy record, the reason for death of people, the annual harvest is clearly recorded over the centuries.

Studying these records and comparing them to years of famine, experts found, if a man encountered hunger when he was under 10 years old (before puberty - when sperm began to form ) his grandson will have a strong hope and live much longer than the average person.

If a man eats excessively (the season is good) at that age, his grandson will have 4 times the risk of diabetes.

For women it is different; If the person is still in the womb (the time when the female fetus' egg is created), the village is starving for decades then, even though they themselves are not hungry, the woman's granddaughter of that woman will there is a risk of dying earlier than a normal person.

In the above cases, hunger does not change genes but leaves a mark on two generations later. This is called transgender effect due to effects on the epigenome genome.

So it can be seen, what we eat, or the age at which we start smoking, the amount of pollution in your neighborhood - these factors are all related to epigenetic changes that can be transmitted so much. system. Equipped with a new and profound perspective on this issue, we can control more about our own health and future generations.

2. The mind can affect the body

A study conducted in the US in 2010 listed the dangers of loneliness. If you have a "full" social connection, you are 50% more likely to live long term than lonely people.

In other words, the effect of having good friends is similar to quitting or significantly reducing the amount of alcohol. A 2012 study of 2,000 US citizens aged 50 and older showed that chronic loneliness led to almost double the risk of death.

Not only that, in older people with poor health, if they have a strong desire to live, they can really live longer.Our state of mind can feel the effect on our bodies, meaning that we have finally learned to better protect ourselves when suffering from the worst devastation of the disease.

Hasse Karlsson, a professor of psychiatry at the University of Helsinki after observing 20 studies of brain changes caused by psychotherapy, concluded that psychotherapy can be used to influence some specific brain circuits. That means, we can use subjective experiences to change the physical structure of the brain.

3. Humans are not a special species

We often think that mankind is the pinnacle of creation but it seems that it is not. In many cases, crows and chimpanzees can use tools like, even better than humans.

If culture is always the pride of human beings, which is what we identify animals without, then perhaps you are wrong. Chimpanzees at Gombe Park, whales in Canada . all have their own cultural activities in the way they connect to sing and hunt.

Not only that, animals also show their personality and morality: elephants can be very sympathetic, but they can be very cold and unintentional. Mice are animals that love fairness, brave spiders, squirrels can look outward or shy and turn out cockroaches also have feelings.

At the present time, researchers have only found some unique human genes. Among them, about 20 to 20,000 genes are exclusive to humans.

In addition, language - the feature that separates humanity from other species is actually quite a sarcasm of evolution. Although the animal world does not have what we consider language, the orangutan gestures are very close to the language.

We have a slightly different body arrangement than the rest, which helps us to speak. But this does not mean, this is a unique feature, our basic difference with them.
