Females Outlive Males

Interesting read from Smithsonian Magazine:

Females Live Longer Than Males—Among Humans and Other Mammals, Too

Women live longer than men by an average of six to eight years, according to the World Health Organization. This intriguing trend is seen in nearly every country around the world, suggesting that it may be driven by profound biological differences between the sexes. And longevity may not be limited to human females; according to a sweeping new study in the Proceedings of the National Academy of Sciences, a range of female mammals live longer than their male counterparts, too.

Among 60 percent of the populations studied, females lived longer than males. On average, their lifespans were 18.6 percent longer, which is considerably higher than the advantage for female humans, who live on average 7.8 percent longer than their male counterparts.

Catch that...... 18.6% longer for females (non-human)!!

WOWZAS!!


Why?  The scientists propose.......
Our analyses suggest that the magnitude of sex differences in mammalian mortality patterns is likely shaped by local environmental conditions in interaction with the sex-specific costs of sexual selection.

Although they are referring to non-humans in that statement, it is kinda funny to read it as if they were speaking about macho male men.   :)


Grace & Peace & Love to you all -
