The main reason women live longer than men

According to a study published in Australia on August 3, the reason women live longer than men is not only because they are less obese, have a positive attitude, less smoking . but also because of heredity.

Scientists at Monash University in Melbourne, Australia and Lancaster University in the UK said that women and men all have mitochondrial DNA, however, only women have immunity. with mutations in mitochondrial DNA. This means that men are more susceptible to mitochondrial DNA mutations than women, thereby negatively affecting life expectancy.

Researcher Damian Dowling of Monash University said: 'This difference does not stem from differences in sex hormones caused by genetic factors. "

Mitochondria are common organelles in eukaryotic cells with double membranes and their own genomes. Mitochondria are considered to be the energy centers of cells because they convert organic matter into usable cell energy.

Mitochondria are also closely linked to the aging process. Although both men and women have mitochondrial DNA, only a mother inherits mitochondrial DNA for her children.

The Australian Bureau of Statistics says that a baby girl at the present time can live up to 84 years, while boys are only 80 years old.
