If you're looking for ways to live the longest life possible, you're already in luck if you're a female. Around the world, women live longer than men. Globally, women have a life expectancy of about 74 years, according to the World Health Organization.

In addition to eating a balanced diet and exercising, there are a number of other, unexpected ways that may add years to your life.

If you’re ambitious about hitting at least 100 years old, researchers have found the following things may help ladies to tack on some years:

Have Children

Women who have children before the age of 60 are expected to live longer than women who aren’t parents by age 60, according to a recent study published in the Journal of Epidemiology and Community Health. Swedish researchers analyzed national registry data of more than 1.5 million people born in the early 1900s. The subjects were tracked as they grew older, and the researchers found 60-year-old women with children had 24.6 expected years of life left, while 60-year-old women without children had 23.1 expected years of life left.

Shop Till You Drop

Retail therapy may help you live longer, according to a 2011 study published in the Journal of Epidemiology and Community Health. An analysis of elderly Taiwanese people concluded those who shopped everyday had a 27 percent lower risk of death than the least frequent shoppers. The authors note these benefits may not have anything to do with the financial aspect, but rather other benefits associated with the experience like avoiding loneliness and getting physical activity through a mall-walking routine, Forbes reports.

Drink Coffee

Women who regularly drink caffeinated coffee may avoid an early death, a study published in the journal Annals of Internal Medicine found. The women who drank at least two cups of caffeinated coffee per day were 25 percent less likely to die from heart disease compared to those who had no coffee, according to a press release. The study authors are quick to note more research needs to be done to better understand the association of having a cup of joe and decreased mortality.

Ditch The Ring

Research has shown that men who are happily married enjoy a longer life than men who are single, but the benefits for women are not as significant. A long-term relationship, without the ring, may be enough to provide health benefits and keep people happy, according to The Daily Telegraph.

If You Do Tie The Knot, His Age Matters

Previous research has shown that men with younger wives live longer; however, this does not apply for women with younger husbands, according to one study. The greater the age difference from the husband, the lower the life expectancy, a study from the Max Planck Institute for Demographic Research in Germany concluded.
