Since 2006, in all countries of the world women live longer than men. However, scientists still cannot quite figure out why this happens.
Why women live longer than men
Researchers from Flinders University looked at life expectancy by gender and confirmed that from 2006 onwards, in all countries females on average live longer than men.
Surprisingly, ladies report more health problems than their male counterparts. There is no scientifically proven and widely accepted explanation why this happens.
The new study looked at the situation with life expectancy by gender through the lenses of epidemiology and sociology. Life expectancy differs from one country to another.
For instance, in Russia women live nearly 11 years longer than men, which is a great contributor to the well-known facts of demographics that there are 86 men for 100 women. In most western countries the difference in life expectancy of males vs. females is about 3-4 years.
For Russia, the difference in the length of life of men and women is often explained by lifestyle factors (drinking alcohol, diet, smoking) as well as cultural paradigms requiring males to take risks and enter physical conflict as a proof of bravery and masculinity. Combined with poor health care and work safety, these factors contribute to early deaths among Russian males.
Certainly, biological factors are also contributors, since the same dynamics is seen worldwide.
Interestingly enough, until recently males lived longer than females. Some scientists link the increased life span of women with the fact that modern women bear fewer kids, thus saving resources that their female ancestors were spending on child birth and raising the offspring.
