We like aggressive music – Strong, sad, full of emotions

We like aggressive music – Strong, sad, full of emotions – We are more willing to choose sad, troubling and full of anger songs. This phenomenon was observed by analysts from Lawrence Technological University. They used an automated system to evaluate the lyrics of the most popular songs listed on the Billboard Hot 100 list from the end of the 1950s until the end of 2016. In total, about 6,000 works were examined. The algorithm assigned each emotional value, and then the average for the whole year.
As Kathleen Napier and Lior Shamir, who analyzed this data, observed, the most optimistic, joyful songs are the oldest ones. From that time on, anger, fear and sadness began to take over to reach the apogee in 2015. Only the middle of the 1970s and the beginning of the 1980s breaks from this trend.
As the researchers emphasize, it does not mean that the music itself has changed

Increasing aggression in the text layer does not mean growing aggression of the creators. This is a sign that the tastes of music consumers have changed

– says Lior Shamir. –

We just want to listen such things.

Human body bacteria – Weight of digestive tract microorganisms

Human body bacteria – Weight of digestive tract microorganisms – The total weight of bacteria
living
in the human digestive system is approx.
1.5 kg. In the large intestine,
we have
100 trillion microorganisms. 10 times more than the number of all cells in the body.
They are divided into
roughly 400 species.

Studies have shown that it is the changes in the number and species of bacteria in the gut
have a negative impact
on the psyche of the patients. According to specialists bacterial flora
may be responsible
not only prone to depression, but depression symptoms in themselves.

At one cm square elbow stays on average 10 thousand. bacteria 113 different species,
