And no - it's not what you might think!
A new study has revealed what Brits think makes for a happy marriage.
The research, conducted by One4All, the Post Office gift card, found over three-quarters (76%) of those quizzed thought that a regular argument or two made for a strong, happy union.
Two thousand UK adults were surveyed for the research, which found an average of 3.9 arguments per month helps keep relationships between married couples stable.
The study also found that going on 3.8 dates, flirting 13.51 times and having sex 8.35 times per month also keep things ticking over nicely.
A compliment or 14.98 (no, literally) doesn't go amiss either, whilst 16.64 meaningful conversations per month will also keep participants in a state of wedding bliss.
Well over half (64%) of those who completed the questionnaire said they look to their parents as their marital example, with 22% citing their grandparents as their relationship inspiration.
In terms of a regional breakdown, couples in Belafast have the most passionate expectations of marriage, believing couples should have sex 10.26 times per month, as well as argue 5.48 times per month.
Manchester couples believe regular meaningful conversations - 17.81 times per month - and 16.17 compliments both keep marriages healthy, whilst Sheffield residents think 5.08 dates per month will help keep things on the straight and narrow.
Aoife Davey, group marketing manager at One4all Gift Cards commented: "It’s healthier to discuss upsets and concerns than to bottle them up. Traditionally, arguing may have been considered unhealthy but actually many Britons now recognise the important role of expressing your feelings - both positive and negative - in relationships. Just make sure that tempers are kept in check, you are respectful and that you are doing the more positive essential components regularly, too".
