why do women usually live longer than men?

Question

real facts and thoughtful opinions only please.. No stupid comments

thank u

Answer 1

Why do men die so young? And why do women die so old? We have no definitive answers to these questions. But the available evidence implicates behavioral as well as biological differences between the sexes, differences in the effects of medical technology, as well as social and psychological factors.
Men are three times more likely to die than women, and most of the male fatalities are caused by reckless behavior or violence. Motor vehicle accidents are the most common cause of death for males followed by homicide, suicide, cancer and drowning. Illnesses related to smoking and alcohol consumption also kill more men than women in this age group. But heart disease is the main cause of the gender gap here. Men experience an exponential rise in the risk of heart disease beginning in their 40s; in contrast, women's risk of dying from heart disease does not begin to increase until after menopause, and it approaches the male risk only in extreme old age. Experts suspect that gender differences in mortality patterns may be influenced at least in part by sex hormones, namely the male hormone testosterone and the female hormone estrogen. Because the male hormone has been linked with aggression and competitiveness as well as libido, some researchers ascribe this spike in male mortality to "testosterone toxicity." Later in life, testosterone puts men at risk biologically as well as behaviorally. It increases blood levels of the bad cholesterol (known as LDL, for low-density lipoprotein) and decreases levels of the good one (HDL, for high-density lipoprotein), putting men at greater risk of heart disease and stroke.
Estrogen, on the other hand, has beneficial effects on cardiovascular health, lowering LDL cholesterol and increasing HDL cholesterol. Estrogen is also an antioxidant--that is, it neutralizes certain naturally occurring, highly reactive chemicals, called oxygen radicals, that have been implicated in neural and vascular damage and aging. Emerging evidence suggests that treatment with estrogen after menopause reduces a woman's risk of dying from heart disease and stroke, as well as her risk of dying in general. Estrogen therapy has also been shown in some studies to delay the onset of Alzheimer's disease.
The Secret to Living Longer
If female longevity is the product of evolutionary forces, then one might wonder what physiological mechanisms have evolved to support the preferential survival of women over men. As we have mentioned, sex hormones are thought to be important factors in determining the relative susceptibilities of the genders to aging and disease. Less obvious is the contribution that menstruation might make to longevity. Because of the monthly shedding of the uterine lining, premenopausal women typically have 20 percent less blood in their bodies than men and a correspondingly lower iron load. Because iron ions are essential for the formation of oxygen radicals, a lower iron load could lead to a lower rate of aging, cardiovascular disease and other age-related diseases in which oxygen radicals play a role. Chromosomal differences between men and women may also affect their mortality rates. The sex-determining chromosomes can carry genetic mutations that cause a number of life-threatening diseases, including muscular dystrophy and hemophilia. Because women have two X chromosomes, a female with an abnormal gene on one of her X chromosomes can use the normal gene on the other and thereby avoid the expression of disease (although she is still a carrier of the defect). Men, in contrast, have one X chromosome and one Y chromosome, and so they cannot rely on an alternative chromosome if a gene on one of the sex chromosomes is defective.

Answer 2

Women are females and in all species females live longer then males. Reason being primarily that females raise and feed the kids. The fact that men are money makers, not hunters, makes no difference to nature. Also once the mortality factor of giving birth had dropped sharply, women really started to out live men. Lastly the fact that a woman's heart (that is designed to give birth) is much stronger then a man, and women in general have heart attacks 10 years or more later then men.

Answer 3

Researchers who analyzed those differences in life expectancy found that pretty much all of the difference was caused by smoking. Women at the time when that data was collected smoked far less cigarettes and certainly less cigars than men.

Now that things are becoming more egalitarian and more healthy, more women are smoking cigarettes and less men are smoking anything. The same is true for any number of other risky behaviours. In the last decade the life expectancies have been getting closer and closer... eventually women will probably drop below men as they do experience risks (a.k.a. childbirth) that men do not.

Answer 4

The statistics for life expectancy include those who die by accidents, murder, etc. Men are more likely to die from these than women (except maybe for the murder part). Men tend to work outside the home more, meaning they are more likely to die in accidents. Also, men have more dangerous jobs, fireman, policemen, military, etc, increasing their chances of dying at an earlier age. Men also are at higher risk of heart disease and colesterol risks than women as their diets tend to be higher in red meats, etc. These are generalizations, of course, but so is your question.

In addition to lifestyle differences, there are some physiological differences that can decrease the life expectancy of men, the primary one being testosterone. High levels of testosterone can suppress the immune system and cause other stresses that can reduce life expectancy.

Answer 5

There are some biological genetic reasons. Men have always been prone to an earlier death, on average. But there are also some other factors that bring down the average life expectancy for men compared to women (e.g. men tend to engage in riskier behavior more often than women.)

Choose a whole-wheat wrap as opposed to two slices of wheat loaf of bread.

Answer 7

One hypothesis as to why women live longer than men has to do with health habits and chronic health conditions. Men tend to suffer from more fatal illnesses, such as heart disease. Women tend to suffer from non-fatal chronic illnesses, like arthritis.

Answer 9

When women grow old, their hearts keep pumping as well as when they were younger, however a man's heart pumps 25% less efficiently.

Answer 10

1.primarily due to hormones
2.they tend to b more happy then men
3.they r more health conscios
4.they have lesser hereditory diseases den men
5.they r less aggressive den men therefore lesser stress

Answer 11

It's so simple it's almost embarrassing.

Body fat.

Women have more body fat and retain more water.

This reduces the effects of oxidising agents.
