People of the future: Men are getting more and more

We all know that women live longer than men. But there is some good news for men: since the 1970s, the gender gap has narrowed. Now, a study published Monday in the journal of the National Academy of Sciences explains the main reason. Surprisingly, the answer is less related to eating less food faster. First of all, since the 1970s, the number of male babies who survived birth has increased.

The study authors analyzed over 250 years of mortality data from 15 developed countries. Since 1751, the probability of men dying at birth is only 10% higher than that of women. But this disadvantage increased until the peak of 30% around 1970. Since then, this level has dropped significantly.

Why? The first is, men are unfortunate people from the beginning. One reason is that the infant's immune system cannot interfere with infection like other girls. Male children are also more likely to be prone to premature birth and must soon experience respiratory distress. The body and head size of a boy's male head also makes them more difficult to produce.

Before embryonic theory began in the 1870s, the authors explained the cause of premature death in babies is due to infectious diseases . When sterility was performed and other medical improvements were achieved in the 20th century, the leading cause of death turned to birth complications. But since the 1970s, more and more babies have been born with child surgery and more infant care centers. These medical advances are helping men to live longer.
