Men grow up early

The son's full puberty is rejuvenated 2.5 months after every decade since the 18th century to the present. In other words, an 18-year-old male now grows to be equivalent to a 22-year-old male in the 18th century, physiologically, a study in Germany confirms.

According to Medicalxpress , science has long proved to be the sooner the time to experience first sighting in girls. However, until recently there has been no corresponding study in boys.

Demographer Joshua Goldstein, director of Max Planck's Demographic Research Institute (MPIDR), in Rostock, Germany, for the first time analyzed data related to mortality rates to prove this trend.

An 18-year-old male now grows to be equivalent to a 22-year-old male in the 18th century, physiologically.

The truth is, there is a direct link between mortality and puberty. The probability of death skyrocketed when male fertility in puberty reached its maximum. This phenomenon exists in all societies and is statistically very complete.

Specifically, puberty boys are completely synonymous with the maximum amount of testosterone hormone . The maximum level of testosterone hormone means that a male boy tends to be most involved in activities that require risky health. Dangerous activities, carelessness, and high violence tend to lead to a massive increase in fatal accidents.

Through analysis, Goldstein discovered that from the mid-18th century, the maximum death value jumped to a time earlier about 2.5 months after every decade, equivalent to two years earlier than every century. Accordingly, the son's puberty also rejuvenates at the same rate.

The stage of puberty is becoming more and more young because the maximum death rate is coming sooner, the study published in Plos one magazine on 16.8 concludes. '18 years old is now equivalent to 22 years old in 1800, in terms of physical maturity. '

The demographer explained the reason for this rejuvenation trend is that better nutrition and the ability to resist the disease of people is increasingly improved.

He also noted that the rejuvenation of puberty in this person is merely a biological issue, not related to the advancement of scientific technology or social activities, because this rejuvenation has It started long before the booming industrial era.

The study also adds that the youthful maturity and social maturity periods of young people are increasingly widening.

'While minors are more and more mature physically, they also officially enter society as a fully fledged social and economic status.'

Life cycle studies have shown that, for more than half a century, the age of marriage, childbirth, entrepreneurship and becoming financially independent from parents is increasing.

This study mainly includes statistical data in European countries such as Switzerland, Denmark, Norway, the United Kingdom and Italy.
