Women outliving men is not a new phenomenon.
Here are a few.
Much like today, the leading cause of death for men during that period was cardiovascular disease.
Heart disease and stroke accounted formore than 40 percent of the increasein male mortality rates between 1880 and 1919.
Forty-four of those chromosomes are autosomeswhich is just a fancy word for chromosomes that are not sex chromosomes.
The remaining pair of chromosomes are the sex chromosomescalled allosomes.
Girls have two X-chromosomes and boys have one X and one Y chromosome.
X-chromosomes are in every cell in the body and carry genetic traits.
Previously, researchers thought the Y-chromosome wasuseless.
However, researchers now believe that defects to the Y-chromosome can cut the lifespan of a man.
A group ofSwedish scientistsfound that men with defective Y-chromosomes had a shorter lifespan.
Older men suffer from age-relatedloss of Y-chromosomes, which is normal and generally harmless.
This also increases the risk of cancer and diabetes.
Girls do it better
Women live longer than men do because girls are smarter than boys.
It might sound sexist, but it’s a scientific fact.
A2015 studyfound female brains develop much faster than those of males.
One study that spanned more than 30 countriesconfirmed girls outperformed boys on intelligence tests.
Countlessstudiesshow that men are more likely to engage in risky behavior than women are.
Men don’t just throw caution to the wind they seek it out.
While that aggression works masterfully in their quest to get women, it also more likelyto get them killed.
It is also important to note, men are more likely to die from work-related injuries.
This is due in large part to the fact thatmen are just more likely to have a riskier job.
I doubt that is one gender gap women will be in a rush to fill.
This is because thehormone estrogenhelps stave off heart disease.
Estrogen helps strengthen the blood vessel walls.
When menopause sets in atage 51, on average a woman’s estrogen levels begins to go down.
This decrease in estrogen causes the walls to weaken and clots to form.
Across many species, larger individuals tend to live shorter lives.
Several studies have found that those who are taller don’t live as long.
A 2013 study found thatlarge dogs were slightly more likely to die youngthan smaller dogs.
Depression and suicide
Women tend to get depressed more often than men.
In recent years, suicide rates among white, middle aged men have increased.
