    Why women outlive men.?
    Women live three or five years longer than men on average in the world, according to the Office of National Statistics. But why?..Have you say ?
    with men being more reckless in their youth and women choosing a better diet and more exercise. But to fully understand why the fairer sex has a longer innings in life, we take a look at the differences between the sexes.
    1.Women tend to have stronger hearts
    A woman's heart is just as strong at the age of 70 as it is at the age of 17
    A study at the university's Research Unit for Human Development and Ageing found that the power of the male heart falls by 20-25 per cent between the ages of 18 and 70. Could this be the key to a lengthier life expectancy?
    2.Women have two X chromosomes
    Tom Perls, founder of the New England Centenarian Study at Boston University believes that the key to longer life expectancy for women is in the genes.
    Where women have two X chromosomes, men have one and X and one Y chromosome which, according to Perls, makes men's cells more susceptible to ageing and damage.
    3. Women may have more powerful immune systems
    Researchers at London?s Imperial College School of Medicine conducted a study of men and women aged 20 to 62 and found that the women produced more infection-fighting white blood cells (or T-cells) than their male counterparts.
    Researcher's discovered that the thymus gland, which produces T-cells, makes fewer cells as people age. Yet older women still had higher levels of new T-cells than men of the same age.
    4. Women tend to sleep better than men
    Women are much better at coping with minor sleep deprivation according to a study by Alexandros Vgontzas of Pennsylvania State University.
    The stresses of modern day life can often mean that we miss out on valuable sleep, which is key to good health, but it is actually men who suffer from sleep deprivation the most: Vgontzas's research revealed that while women manage to get an average of 70 minutes deep sleep each night, men only managed to ****** 40 minutes.
    5. Women generally have healthier diets
    If you think your man behaves like a caveman - especially when it comes to his eating habits, here?s why.
    A survey by FoodNet of 14,000 men and women found that men are more likely to eat meat-based dishes while women opt for a variety of foods including fresh fruit, vegetables, nuts, eggs and yogurt.
    6. Women remain healthier in order to reproduce
    The roles that men and women play in the circle of life are very different and may determine why women outlive men.
    Thomas Perls, a former geriatrician at Harvard Medical School, believes that the menopause protects older women from bearing children in later life and allows them to live long enough to take care of their families.
    Perls also says that a man' purpose is to ?carry genes that ensure longevity and pass them on to their daughters. Thus, female longevity becomes the force that determines the natural life span of both men and women?.
    7. Women are less likely to be smokers
    Smoking causes around 18% of deaths in adults aged 35 and over every year in the UK, according to the NHS. Shockingly, the NHS estimates that 23% of men will die of a smoking-related disease, compared to 14% of women.
