(CNN) - Each year when Valentine's Day approaches, our thoughts turn to love, relationships and coupling.
A 2015 survey from the American Academy of Dental Sleep Medicine found "40% of women claim snoring in the opposite sex is a turn-off, and nearly one in 10 Americans went so far as to admit that snoring has hurt at least one of their romantic relationships." Snoring regularly affects 37 million sleepers.
For singletons, snoring probably isn't as much of an issue -- and every night doesn't feel like an eternity. Getting hitched can really add up, for all concerned.
Researchers from the University of Utah found in 2009 that middle-aged women in unhappy marriages showed risk factors for heart attacks and diabetes.
If you're single, you may be more motivated to get in shape to look attractive for potential mates.
Coupled cancer patients were also 17% less likely to see their cancer spread.
They have a lower risk for heart problems as well, says a 2014 study from the American College of Cardiology.
Depending on income, some are eligible for bonuses and certain deductions where singles aren't, but in certain situations, they are responsible for paying a tax penalty that could eat up a large portion of their combined salaries.
For Social Security, one partner can claim a full spousal benefit, which is equal to one half of your husband or wife's retirement benefit.
The Better Sleep Council found that 26% of the coupled people they surveyed in 2012 got a better night's sleep when they slept alone.
It seems like many people aren't getting enough sleep anyway, no matter what their relationship status is.
While there are certainly perks to both lifestyles, when is it better to be coupled up, and when is it better to be living the single life? According to the US Census, 128.8 million of Americans 18 and over were married in 2016, which translates to 52.7% of the adult population.
