The key to longer life might be found in your relationship status.
A new study by Duke University Medical Center found that Baby Boomers with permanent partners or spouses had a decreased risk of premature death during midlife years, Science Daily reports. Individuals who were never married were more than twice as likely to die early than individuals who had been in a long-term, stable relationship.
More than 4,800 people born during the 1940s took part in the study, and the authors controlled for personality, socioeconomic status and health risk behaviors. Still, being single or without a consistent partner during middle age increased the likelihood of early mortality.
The study echoes other research findings on marriage and health, such as this study that found that married couples experience lower levels of heart disease and cancer.

Online Gaming Can Hurt Your Marriage
According to a Brigham Young University study, couples reported <a href="http://healthland.time.com/2012/02/16/is-online-gaming-messing-up-your-marriage/">lower marital satisfaction</a> when one spouse's gaming interfered with bedtime routines. Seventy-five percent of gamers' spouses wished their partners would put more effort into their marriages; however, when both spouses gamed, a majority reported greater satisfaction in their relationships.
The "Honeymoon Phase" Is A Myth
It turns out couples are happiest <a href="http://www.huffingtonpost.com/2012/12/04/marriage-research_n_2234804.html?utm_hp_ref=marriage">AFTER their first year of marriage</a>, according to an Australian study. Newlyweds were found to have a lower happiness score than couples who had been married longer. Researcher Melissa Weinberg attributed this to a "wedding hangover," or the depressed feeling couples get when the wedding is over and the marriage begins.

Getting angry can help signal that certain behavior from your partner is unacceptable, said lead researcher James McNulty.
Cohabitating Couples Shown To Be Happier Than Married Couples
A study released in January found that while married couples exhibited health gains (most likely due to marriage benefits such as shared health plans), unmarried cohabitating couples experienced <a href="http://news.health.com/2012/01/23/living-together-may-be-mentally-healthier-than-marriage-study/" target="_hplink">greater happiness and self-esteem</a>.

The Later You Have Sex, The Better Your Relationships
Researchers at the University of Texas at Austin found that having sexual intercourse at a later age corresponded with <a href="http://www.huffingtonpost.ca/2012/10/19/virginity-and-marriage-_n_1981755.html?just_reloaded=1">less dissatisfaction with relationships</a> in adulthood. Higher education level and household income also corresponded to a later age of first sexual experience.
Interracial Marriage Rates And Acceptance Rising
Not only are <a href="http://www.cnn.com/2012/02/16/us/interracial-marriage/index.html">more interracial couples marrying</a>, but interracial marriage is more widely accepted than ever before. In 2010, 15 percent of new marriages in the U.S. were between spouses of different races; in 1980, only 6.7 percent of marriages were interracial.
Married People Are Healthier, Live Longer Than Singles
<a href="http://cleveland.cbslocal.com/2012/11/14/study-married-couples-live-longer-healthier-lives-than-singles/">Studies show</a> that married couples experience lower levels of cancer, heart disease, depression and stress. The health benefits are even more pronounced for marrieds than for couples who are simply cohabiting.
Young People Expect Marriages To Last
A survey found that 86 percent of single and married people aged 18-29 <a href="http://www.huffingtonpost.com/2012/08/17/marriage-expectations_n_1784371.html">expect their marriages</a> to last a lifetime. Researcher Jeffrey Jensen Arnett told HuffPost that young people tend to have a romantic view of marriage and go into marriage determined to make it work.
Married Women Drink More Than Single Women
A <a href="http://www.huffingtonpost.com/2012/08/20/marriage-alcohol-study-wives-drink-single-women_n_1810133.html">study on marriage and alcohol</a> found that women drink more after getting married, possibly because they are influenced by their husbands (on average, men drink more than women). Men, on the other hand, were found to drink less after getting hitched.
Son-In-Law Key To Successful Marriage
Here's another reason to get along with your in-laws -- unless you're a woman, that is. A <a href="http://www.huffingtonpost.com/2012/11/27/in-laws-and-marriage_n_2199637.html">26-year longitudinal study</a> found that when a husband reported having a close relationship with his wife's parents, the couple's risk of divorce decreased by 20 percent. Conversely, when a wife reported having a close relationship with her husband's parents, the couple's risk of divorce increased by 20 percent.
